Your name, as a pattern
Type anything. The same name always gives the same picture — on any device, on any day. Nothing is sent anywhere.
The link carries the name, so whoever opens it sees the same picture.
How it decides
The name is turned into one number, and every choice after that comes out of it: which palette, how many petals, which shape they take, how far they lean, how many rings, where the dots sit. Nothing random is involved, which is why your picture is still your picture tomorrow.
No accounts, no cookies, no analytics, no server. The name you type is used to draw a picture and then forgotten.
