A peek behind the paint

How this was made

3D Lab began as a pile of big ideas and a blank sheet of paper. Here is what is hiding underneath the paint.

  • Painted by code

    Every picture here was painted by a tiny watercolor engine written with Python and OpenCV. It copies real pigment: soft wet edges, color pooling where it dries, grainy paper and little blooms where water creeps back in.

  • Layers that move

    Each card is a stack of see-through painted layers. A sprinkle of CSS and JavaScript makes planets orbit, pistons pump and ducks bob, and it all naps when you scroll away.

  • A team of three

    Dreamed up and directed by josephpnc, and built side by side with Claude and Codex, two AI coding helpers. Plenty of “what if…?” went back and forth until it felt just right.

  • Light as a feather

    No servers and no databases: just simple pages that load fast anywhere. Close this note and tap the page to leave a splash of your own.
