“Tried bangs on every coworker's photo. Two of them actually got bangs the next week. I don't know if that's correlation or causation.”

The demo
What it looks like when it’s working
In the room · 45 minutes
What you’ll build
Upload a selfie. Pick from preset hairstyles. AI does a virtual hair try-on via Vertex AI image generation — same person, new look — and shows before / after side by side.
The moment it clicks
“OMG that's me with bangs.”
Things to think about
While you build
- Hair only today. No outfits, no facial filters — those are the polished version. The constraint is what gets you to ship.
- Your signature detail is what makes your app yours. A sassy stylist note? A vibe rating? Decide before you start typing.
- Test on a face you don't recognize first. You'll catch prompt issues faster when there's no emotional read on the result.
The 2-hour Jam rhythm
How the night flows
Every Coding Jam follows the same five-phase shape. Talking is short, building is long.
- 0:00 – 0:05Intro
Welcome, name tags, snacks within reach. The facilitator sets the tone: low pressure, high creativity, ship something messy.
- 0:05 – 0:15The Demo
Facilitator demos the polished version of tonight's project. Live or pre-recorded. The message: this is what's possible.
- 0:15 – 0:25Spec Talk
Walk the 5 questions on the projector. The output is a one-page PRD that Antigravity will turn into UI + engineering docs.
- 0:25 – 1:30Build (codelab)
Participants run the codelab. Antigravity writes the code; they direct it. Six phases inside this hour: Setup → Plan → Review → Build → API → Verify. Fix the doc, not the code.
- 1:30 – 2:00Sharing
Three volunteer screen-shares. Celebrate the messy, brilliant, half-finished prototypes. Quick wrap-up. Tease the next jam.
Polished version pulls in
Where to take it after the jam
The 45-minute build is the win in the room. These are the ideas you can pull in over the next week — your homework isn’t homework, it’s the polished version.
- Outfit and accessory modes
- Custom typed-in prompts
- Share button
- Side-by-side compare
- Lookbook to save favorites
- 'Rate my friends' group photo
- Decade time machine

“Outfit mode kept giving me looks that were too LA. Then I changed one prompt word and everything got weird and wonderful.”
