RECEIPT

Fork the starter repo. ...because I need to ensure it works in the constraints of my printer. Sowwy
Make it yours. Edit sketch.js and see how it'll look. Once it's yours you need to ship it.
Ship it. Ship Ship Ship... and wait! I'll print it on a receipt printer and send it to you. Maybe I'll drop some stickers too ;>

What can I make?

Generative art, procedural art, a tiny comic, a weird pattern -- anything you can make with code and fit on a receipt.

What size is the receipt?

384 pixels wide, 240–2000 pixels tall. The editor turns your final artwork into pure black and white.

What do I submit?

A public link to your repo and the PNG exported by the editor. You'll also need at least one hour tracked in Hackatime.

Will you actually mail it to me?

Yep! I'll print your art on a receipt printer and mail it to you.

When's the deadline?

Submit your receipt by September 23, 2026.

okie bai bai
