Inspiration
Y2K dress-up games like Stardoll, but with real AI. Meta Glasses + Gemini Vision felt like the perfect way to bring that pure pink-and-glitter energy back.
What it does
Snap a photo with Meta Glasses. Gemini Vision reads the person's vibe and generates a pixel Y2K avatar like skin, hair, outfit, archetype. Dress them up in the closet, then hit the Slay Floor where everyone dances together with disco ball twinkles and chat bubbles.
How we built it
React + Vite frontend with fun Y2K styling. Cloudflare Workers backend with Durable Objects for realtime, R2 for photos, and Gemini 3.1 Pro via Vertex AI. Avatars are layered LPC sprite sheets cropped with CSS. WebSockets handle dance and chat sync.
Challenges we ran into
Cropping sprite sheets to one frames, lifting outfit state so it persisted between screens, and most notably Gemini API limitations caused a few rounds of bugs.
Accomplishments that we're proud of
A full end-to-end photo to AI to dancing avatar pipeline in under 6 hours. A dance floor that feels alive even with no users thanks to frontend bots. And a genuinely cohesive Y2K aesthetic top to bottom.
What we learned
Good AI UX is mostly schema validation and graceful fallbacks. LPC sprites are a hackathon superpower. Frontend bots solve the cold-start problem better than backend seeding.
What's next for BitBabe
More outfits, hair swapping, shared backend bot state, and eventually an AR mode connecting to augmented reality glasses.
