The demo

What it looks like when it’s working

In the room · 45 minutes

What you’ll build

Upload a photo — your face OR your pet's face. Pick from four preset styles (e.g. Pixar, anime). AI returns one stylized avatar.

The moment it clicks

My cat looks like a Pixar character.

Things to think about

While you build

  • Your input rules are the design — faces only? full body? pets too? Pick one rule and stick to it. It shapes every prompt you write.
  • One avatar at a time. Bulk generation, animations, multiple sizes — all polished version.
  • Assume people will share these — your output is the marketing. Pick styles that screenshot well.
The 2-hour Jam rhythm

How the night flows

Every Coding Jam follows the same five-phase shape. Talking is short, building is long.

  1. 0:00 – 0:05
    Intro

    Welcome, name tags, snacks within reach. The facilitator sets the tone: low pressure, high creativity, ship something messy.

  2. 0:05 – 0:15
    The Demo

    Facilitator demos the polished version of tonight's project. Live or pre-recorded. The message: this is what's possible.

  3. 0:15 – 0:25
    Spec Talk

    Walk the 5 questions on the projector. The output is a one-page PRD that Antigravity will turn into UI + engineering docs.

  4. 0:25 – 1:30
    Build (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.

  5. 1:30 – 2:00
    Sharing

    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.

  • Generate multiple avatars at once
  • Animated avatars (subtle motion)
  • Full character lore generator (name + backstory)
  • Social media format presets (Twitter PFP, Discord, LinkedIn)
  • User-defined style prompts
If you get stuck

Open one of these in the starter — safety nets, not requirements.

Self-portrait in oil-painting style felt like a souvenir from a dimension where I went to art school.

Showed my golden retriever as a Pixar character to my coworkers. Got asked three times to make their dogs too.
