Need to generate animated GIFs that actually work in Slack? This gives you a GIFBuilder class, easing functions for smooth motion, and validators to check Slack's specific requirements (128x128 for emoji, certain color limits). You draw frames with PIL primitives like ellipses and polygons, then the toolkit handles optimization. The docs are solid on animation concepts like bounce, pulse, and particle bursts, plus it pushes you to make things look polished with thick lines and gradients instead of basic shapes. It's not a template library, more like guardrails and utilities so you don't have to remember Slack's quirks while coding frame-by-frame animations.
