M$TH Lab Simulator by OPUS 5.5 👀
Audio was generated using Gemini 3.8 Flash TTS (guided by opus)
Astra can COOK! ⚗️🧑🔬
M3TH Lab Simulator — built by GPT-6 🤗
Gave it a try. 🔥
Creative and actually fun , writing stuff into the world and then walking around in it feels nice
🚨 i built a world you write into existence
worldpen: describe any world, claude builds it around you, then you walk in
> write a dragon that chases you. then ride it
> sketch a whale in your notebook. it steps off the page
> talk to an elephant. it remembers you
> fire spreads, rain puts it out, glass shatters
> hold R and time runs backwards
> one sentence turns it into a game
> days pass, seasons turn, it keeps living while you're away
> drop in a painting and step inside it
> flip to 2d: 9 art styles, from storybook to pixel
all of it in one html file, built with claude
stay for the pixel dragon 👀
