Commentary

A real eye-tickler. This was one of the first bits of <canvas> code I ever wrote; I essentially wrote it by accident — it wasn't quite what I meant, but I liked it, and kept it. For me, in Firefox, it starts getting interesting around 100 iterations, and starts stopping being interesting around 1550. In Chromium, you can still see some activity at about 2000 iterations, but it's very faint thereafter.
