The demo
What it looks like when it’s working
In the room · 45 minutes
What you’ll build
One text box: type what's on your mind. AI generates a mood sticker/item — kawaii emoji, glowing orb, tiny potion, pixel-art object — and drops it into a visual 'jar' on the page. The jar fills up as you keep writing.
The moment it clicks
“My scattered thoughts just turned into a cute little token in my jar.”
Things to think about
While you build
- The visual aesthetic of the tokens IS the soul of the app. Kawaii emojis, glowing orbs, tiny potions, pixel-art objects — pick a vibe and stay there.
- The jar is a simple container today. No physics, no falling animations, no settling — that's the polished version. Items just appear inside.
- No persistence across sessions. The 'jar that fills over weeks' is the magical polished version — leave it as a reason to come back.
- One token per submission. Don't generate a grid of options. The serendipity of one is part of the feel.
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.
- Local storage so the jar persists
- Animated physics (tokens settle, jar tilts)
- Multi-day pattern detection
- Cross-device sync
- Mood history charts
- Share-your-jar mode
- Voice memo input

“Rewrote the personality prompt three times. Each version felt like a different friend. Settled on the gentlest one.”
