I built a simple web app for my kids to color a character template, then see their creations dance on a screen (almost instantly). It was inspired by the Crayola Experience in Dallas.

I first built it as a weekend project for my daughter's Halloween party at school. Then my son asked to do it at his Valentines party. Then a friend asked me to run it at their STEAM party.

The code is a bit of a dumpster file - hacked together in a few weekends. Wish I could say it was vibe coded, but nope. I'm just that bad at animation stuff.

Tech stack: NodeJS, ThreeJS for animation, QR code scanning (zxing-wasm) for template detection/alignment, and Adobe Mixamo for the dance animation.

Anyways, I wanted to share in case someone would like to use it for their kids. It's got readme instructions if you want to customize the characters and background.
