hello

A six-digit odometer reading 000201 over a field of translucent circles — you are visitor **#201**

This page is served by a Raspberry Pi sitting in a house in England. Every visit bumps a number on its SD card, and that number seeds the picture above — the colours, the circles, all of it. Yours is the only one that looks like that.

Go, no dependencies, no JavaScript. The image is drawn with the standard library's image package, a pixel at a time, and embedded straight into this page — it has no address of its own, so nobody can go looking at anyone else's. source
