A crusty piece of code I still like after all these time: haywire. If I remember correctly, this is a prime example of a coding accident. Originally a 2D experiment in tracing curves, it got an unexpected sense of depth when I mistyped the
translate used in the particle drawing routine. To me it looks like the aftermath of an extremely complicated clock going cuckoo.
Although not readily apparent from the code, this piece is a precursor of curvature. Both constructs keep track of drawn curves by filling an invisible grid. When the tracing particles hit an already filled space, the curve is stopped and reincarnated. This mechanism is obfuscated in haywire by the artificial depth offset. But if all curves would be drawn on the same plane, the resulting image would resemble those generated by curvature.
