I built sketchling this weekend to see if agents can draw something that looks natural and hand-drawn if given the right primitives. This was inspired by Manim after watching how powerful an agent-native way to produce animations can be.It is a small typescript library with shapes that take character parameters like weight, looseness, and energy. It renders through rough.js and GSAP through a headless chromium browser. It has tools like a built-in linter and is meant to be agent-native.As a test, I gave the library to Devin cold with minimal instructions and it came back with a 3 minute, 9 scene short film which I found cool! I also had 5 more agents each try a different style, pixel art, clean line, clay, 3D, even a jazz club scene with its own music, and they all came out looking different which was awesome to see.I have added procedural walk cycles, camera movement, particle movement, and a small sound library as well. It is very early and has Chromium and ffmpeg as dependencies, which is more setup than I would like. I m also honestly not sure how far this goes past the kind of demos I ve shown here. Would love any and all feedback!
