Let There Be

Type a word. Watch a universe be born from it.

One self-contained HTML file. Type any word (a name, a feeling, anything) and a universe is born from it in real-time 3D, with its own sound. Headphones recommended, and the REC button saves what you create as a video.

The prompt, in full

Build me something when people see it, they will say "Wow". Must be immersive, when people see it, they will be stunned by what they see.
This can be a video, or anything else you can think of.
Be creative. Go wild. Dig deep.
No AI slop. Something unique, think outside of the box. Think big. Think amazing. Something no other model done before.
Be proud. Show your best. Don't disappoint.

100 HTML Files

One challenge, 16 models, everything published.

Each model gets 100 creative briefs, from generative art and physics toys to editorial layouts, games and small tools, and writes every one as a single self-contained HTML file: all CSS and JavaScript inline, no libraries, no external assets. Every gallery shows each page next to the exact prompt that produced it.

Retro Tetris

Four models, four hand-drawn takes on falling blocks.

Four complete games, each a single self-contained HTML file with no install and no backend, and each in its own visual language: colour pencil on graph paper shot on 16mm, a paper arcade cabinet with film grain, an ink sketchbook film edition, and crayon on a wobbly pencil grid.
