Great idea.
Hopefully this will keep everyone happy – I just signed up for $150.

Please take a second to think about how screwed you would be if TweenLite/TweenMax wasn’t around or GreenSock stopped updating and fixing it.

Posted by Michael Dragich on April 10, 2008

I’m enthusiastically in for “Shockingly Green”. Glad to see GreenSock offering ways to monetize your work with extras, while simultaneously not precluding the poor geeks from using the core classes. How enlightened of you, in a Prince/Radiohead/NIN kind of way :)

Three forest green cheers for the world’s favorite benevolent class developer!

I didn’t even realize that by going Shockingly Green I’d be getting all these nice bonus classes- can’t tell you how useful they’ve been!

Come on people, we need to buck up for at LEAST $150, this is a steal of a deal for GreenSock’s hard work that will save you countless hours, days, even months of frustrating development time!

Think about how pwned you’ve been paying thousands for a CS3 package that can’t shortcut you to any ends like what these great classes do! The more you support GreenSock, the better YOUR projects will be, for way less than the cost of half of Flash!

Keep up the good work. We’ll continue to support you!

Posted by rOcK on April 29, 2008

Excellent work Jack! I have been using flash/flex on and off for about 6 years and had been a big fan of a different engine. But more recently, I came accross a demo doing full screen zoom/pan and it was smooth as silk. Sure enough, it was using TweenLite!

After doing some more research, checking the various performance comparisons and trying the libraries out for myself I was more than happy to go shockingly green!

Great value for such an awesome set of components!


Posted by Haungo on April 30, 2008

I just got an amazing new job as a partial result of building some badass projects using TweenLite. It wouldn’t have been as quick or smooth without it. So, come next paycheck.. I’m going all kinds of Green!

Thanks for doing and loving what you do!


Posted by Erik Hallander on July 15, 2008

Best $ I spent in my life.

Posted by Erik Hansen on August 17, 2008

I just threw in my $50! Can’t wait to get the extra tools :)

And, to second (or third) what others have said, take a moment to think about how much easier GreenSock has made your life with these classes. What a great contribution to the community.


Posted by WLM on October 17, 2008

I thank you on my bare knees for the extra classes that came with the Shockingly Green package!

These tools represent the best investment you can do as a developer (I earned the money back within one project because of the time saving features of TweenMax and the bonus classes).

Keep up the good work!

Greets from Holland,


Posted by Taï-nui on October 19, 2008

Hi Jack,
One of the first times I have donated since it’s (almost) always possible to find things “for free” on the internet, but i really enjoy your code and think it’s well worth paying for ; )
It is simply incredible and saved so many hours of coding … !

Many many thanks

Posted by Keyriest on November 10, 2008

these classes have become de facto tween packages in all my projects now. I rarely even use the timeline anymore, as these are far more powerful and controllable.

Posted by Gerry Fontaine on February 4, 2009

Thanks GreenSock for all the questions you have answered. People should know that you stand behind your code, and that when it comes to tweening classes your code is second to none. You have me hooked for life.

Posted by PlugFour on February 18, 2009

You had me at ‘transformAroundCenter’. Well done, sir.

Posted by hugo on March 4, 2009

Congratulations… i just can’t live without these tools… I have been using them for sometime now and they are a milestone in all my Flash projects!

I must say I admire your distribution policies. As a freelancer I have made a rule that all my work is done with “legal” software (including fonts) and I think that the possibility of being able to use “simple” versions of your classes an amazing step… the possibility to choose one’s membership plan… heaven on earth :)

congratulations for your amazing contribution!

Posted by erik on May 1, 2009

I’ve only just begun to familiarize myself with GS, and I’m blown to pieces by it’s capabilities! I will certainly donate as soon as I start using it to get access to the rest of the classes, it’s tax deductible anyways for crying out loud!

Posted by Bruce on October 1, 2009

BezierPlugin alone was enough to convince me that I needed to be Green. I struggled with moving objects along a curve for several days before finding TweenMax and BezierPlugin, so a membership was well worth the price.

Please! keep up the great work.

Posted by Benjamin on October 22, 2009

Feels good to be green at last!
It’s always nice to be able to give something back.

Posted by ecukit on October 25, 2009

$50 will save your 100+ hours

Posted by Klark Kent on November 19, 2009

Ive been using many different tweening classes over all those years… nothing ever compared to what you have been doing here… and i seriously NEVER wanna miss this again. Keep up the good work

Posted by Joshua King on November 20, 2009

Just gone Green!
Best Classes out there


Posted by Tahir Ahmed on November 20, 2009

I love GreenSock’s tweening platform for a long time now and I would certainly encourage all the developers using it to donate for Jack’s great work. I am a Shockinly Green member and I am so happy to get those bonus classes.

Best of luck Jack and keep on surprising us with every new version of this platform.

Posted by Ian on December 10, 2009

Just signed up because this is actually the one platform that I just couldn’t live without.

Greensock, thanks for the great work!

Posted by Swader on December 11, 2009

Gladly signed up! Thank you for the fabulous work, your classes turn AS3 into pleasurable pastime instead of work.

Posted by Rodrigo on January 8, 2010

I just tested the new SplitTextField among other recent additions to the TweenLite platform and I wanted to say that I’m very impressed for such a great work. But that’s not all. I’ve contacted Jack in a couple of times with support questions and his responses are extremely fast, helpful and friendly. It’s not exagerated to say that a world with more “Jacks” would certainly be a better world. Cheers!!

Posted by one giant media on March 4, 2010

Well, it’s been about a year since I first signed up, and I can say I am happily back to sign up again, and for good reason! I’ve used this library in almost every project I create now. It’s only gotten better in the past year – smoother, faster, more classes, more capabilities – and always great quality reliable code. Oh, not to mention nice testbed apps that show you live source code to really spell it out for us n00bs. I feel pretty lucky that this library is available for $99 bucks. Even the commercial license is a steal. This workflow is starting to be more powerful than Adobe Flash by A LANDSLIDE. Keep up the good work GreenSock!

Posted by Byron on March 8, 2010

After downloading, checking out the code and working through some examples, all I can say is wow! and thank you for all of this work! And thank you for including those cool explorer apps with the download. You are awesome and I wish you all best. I will definitely support you and spread the word.

Posted by Pharmboy on March 28, 2010

OK, so my membership is expiring. And I’m back to renew AND upgrade to Shockingly Green, happily, happily. The classes, the support…topnotch. To be honest, for most of what I do the free stuff would suffice, but I really like being able to throw my support to someone who really does a bang-up job for all of us. Thanks, GreenSock!

Posted by David Rueda on June 22, 2010

Amazing stuff… i´ve been using GS for quite a while now… It has saved me hours and hours of painful job… Thank you for making our work so much easier… Im proudly green now…
Greetings from Guadalajara, Mexico!

Posted by Roel Beckers on June 23, 2010

Really great what greensock is providing to us! amazing work and BIG BIG thanks…
Gonna discuss a corporate account with my employer!

Posted by Guillermo Simeon on July 11, 2010

I am so glad to finally get my corporate license. I have a few project that will REALLY profit from this corporate membership. Your library just rocks and I can’t imagine myself not using it these days.
It saves me loads of time and is so powerful.

Posted by Ben on September 2, 2010

Discovering TweenLite (and all of your products) was a defining moment in my career and has forever changed the way I create apps.

Posted by Guilherme Souza on November 23, 2010
Who is the boss of the Tweens ?

Posted by Albert Papadosifakis on December 21, 2010

The most well spent money I had the past years . $99 is an ok price to pay for all the goodness we receive. Keep it up! Cant wait for your new stuff!

Posted by Samuel Asher Rivello on January 15, 2011

Great work!

I didn’t become a member to get any ‘extra’ stuff. I just wanted to thank the great team that made my worklife better with its TweenMax and LoaderMax.

You rock!

Posted by Richard on January 29, 2011

I have been using your code for a good while, but lately it has been especially useful to me. I have also been wanting to post a comment here thanking you for your amazing work. However, I didn’t want to do so until I had a paid membership, to fully emphasize my gratitude. I am happy to now be a corporate member. I owe you a tremendous debt of gratitude. And, for what its worth, I can tell you that every Flash person I meet here in Atlanta begins their projects with this line:

import com.greensock.*;

Posted by Peter Lewis on March 25, 2011

Boy did I mess up in purchasing only the “Green” membership. I feel like a total moron after buying it and figuring out that your product is so BadAss that I should have gone “Shockingly Green”.

I had tried very hard at figuring out other crackhead solutions to some crazy interactive issues with some clients that I was about to give up and refund my customers money.

Now that I have full faith in your product in how easy it was for an idiot like me to figure out, I wanted to see what it takes to upgrade your product to the Shockingly Green Version, or do I have to buy a second license?

Let me know so I can happily spend more money with you to utilize more tools. Please, Thank you parents for me, for finding each other, falling in love, and having sex to produce a genius like yourself.

Greenfully yours,


Posted by Jack on April 14, 2011

Peter, that’s hilarious (the “thank your parents” line). Glad to hear the tools have been useful. To upgrade within 45 days of your original purchase, just go ahead and purchase the new membership (in your case, “Shockingly Green”) and then send me an e-mail request for a refund on the original purchase. Thanks for your support!

Posted by Zen on August 8, 2011

Hi Jack,

First of all, thanks for a masterful class like this. I can’t put it in any other words on how much i appreciate this. Cheers! :D

Posted by geckzilla on December 12, 2012

Ahh, how far you’ve come since the day I donated my paltry $5 through the old Paypal link… you are still the tween master wizard!

Posted by kt on January 24, 2013

I’m getting mine license next week thanks so much Jack for creating a masterpiece

Posted by Allen on June 20, 2013

Just signed up for Shockingly Green. Really didn’t need that level, but GreenSock rocks! How could I not contribute a bit more to continued development?

Posted by Jack on June 20, 2013

What a nice gesture, Allen! Great to have you on board. As far as contributing to ongoing development, one of the most helpful things you can do (besides joining Club GreenSock and spreading the word) is simply helping in the forums. Not only does it give a richer experience to others there, but it helps us to be able to focus more time on development rather than answering questions (which can take a surprising amount of time when there are only a few people providing answers). Added benefit: most people who have gotten involved in answering questions there say it has been a great way for them to learn more themselves as well.

Thanks again!

Posted by Eli Israelian on July 8, 2013

Can we sell web themes that include gsap to web theme markets?

Please say yes :)

Posted by Jack on July 8, 2013

Absolutely, Eli, you can sell themes that include GSAP as long as you have an active “Business Green” Club GreenSock membership – that’s the one that gets you the special commercial license for selling things to multiple end users. See to sign up or for details about licensing. I think you’ll find that the membership pays for itself very quickly.

Posted by César Cid on July 11, 2013

Hello , may be a great idea if you add presets to gsap library. example: . a extend package with most used effects by users. Regards and congratulations for this awesome library.

Posted by Grot on August 22, 2013

I’ve renewed the membership recently. Looking in my account I was already green in 2008 ;-)
When Jack started this there were a few (flash) libraries around but trying them out it didn’t take long before I wanted to go back to programmatically tween all my animations myself again… Most of them were slow, had bad support or no AS2/AS3 flavours…
After trying the Greensock libraries I thought “Well, this is something I could get used to!” Fast, flexible and a helpful creator plus community!
And… When Flash really started to get dumped for JavaScript websites the Greensock libraries were there already to help me out – again. Thanks for the perseverance Jack!

Posted by Nerd on September 18, 2013

I promise, I will buy a Business Green License, wait until i have enough money for it. :D, thanks for your great plugin.
