Project Tabletop 1.3 is ready!

Play Stryker's Run, paint with physical markers, and explore Earth on a projected tabletop.

Which board would you try first?

here’s how to build an ori-style platformer with gpt image 2.5 + tripo + claude opus 5.5...

playable on desktop and mobile

the trick is “make it exist first, then make it good”, there’s a smart way to set it up:

- step 1: mock up the mood in gpt image 2.5: night storm, piers, wrecks, one glowing boss
- step 2: turn the mockups into 3d models with tripo p2: the giant, the ships, the piers, the buoys
- step 3: clean the models up in blender: scale, pivots, low poly so they run on mobile
- step 4: make the hero a 2d sprite (run, jump, attack) and drop it into the 3d world
- step 5: have opus 5.5 write the game: movement, jumps, camera, rain, water
- step 6: build the boss around one readable rule: the giant’s light shows where its fist will land
- step 7: add sfx and music from elevenlabs
- step 8: deploy to vercel and send the link

ship an ugly version that works before you polish anything

a playable grey box beats a beautiful mockup

@geygitarguy @Belbizaz @threejs Tell your AI to implement:
- Thresholded bloom
- screen-space Ambient occlusion to enhance where joints and objects meet
- Distance fog and added light haze
- Particle sprites, some catching the bloom

@OpenAI I had an amazing experience with Astra today! I noticed it split work to several subagents <3
Please Sir, may I have some more?

@Cryptofuture46 @ShakilZen indeed, the 9 seems over-engineered 🤣

@CodexResets1 What GPT model do you use?
I use Claude (Opus 5.5) to review Astro's code (on a $20 plan, the 5-hour window is good enough). Then go back to Astro to review the fixes and commit.

@thsottiaux implementing a new board for my "Project Tabletop"

[Alexander Biemann @alexbiemann]

Project Tabletop 1.2 is out! ⚽

A projector, webcam, and printed markers turn your floor into a football pitch. Take on a friend or the computer, with a VERY bouncy ball, stadium cheers, and victory confetti!
