Hello HN,I created a simple website which lets children (of all ages) sketch something and then animate it using AI. It's a small hobby project because I wanted to see what all the hype is about.No account required (but because the sketch app allows image uploads and we all know we can't have nice things on the Internet, I will be moderating the submissions before showing them on the front page).Stack: Excalidraw, Django, Postgres, Redis for caching, ComfyUI for the image to video workflow (Wan 2.2 14B I2V).Let me know what you think. Merry Christmas!

Feature requests: Optimize for tablet use, Improve prompt engineering (positive and negative prompts), Keep original sketch in context or reintroduce halfway through animation, Steganographic injection of sketch to improve style matching, System-level prompt tuning to reduce 'funkiness'
