Make virtually any DOM element draggable, spinnable, tossable, and even flick-scrollable across devices (mouse and touch), complete with momentum-based physics, snapping, and more.
Chris Gannon shows how he built a draggable 3D carousel with GSAP. We'll call it "CubeDial". It's pretty slick.
Visually explore various eases that are available in GSAP with this interactive tool.
There are some interesting (and surprising) performance implications of using CSS animations that aren't widely known. Check out this video demonstration.
