“ If every library were as robust and reliable as GreenSock’s, the world would be a much better place for software engineers and their clients. I can't think of a better designed or better performing tool, and as a bonus, it's fun as heck to play with. ”

Thomas Summerall

“ It's shocking the @w3c didn't use @greensock as a model of how to do animation via code. Did they even ask animators what they use? ”
