opposite corner thirds

Description

I like the contours. It's not obvious which features contribute most to the apparent wedges. The average brightness is constant across the image, over any suitably large averaging window. The symmetry is not immediately apparent: there are "dark" wedges pointed to upper-left and corresponding "light" wedges pointed to lower-right.

It is curious that I like these repeating high contrast patterns: I have a serious problem with migraines and this is the type of stimulus that most aggravates the condition. Perhaps staring at these patterns causes my migraines.

This is the top left corner of a larger pattern.

Description

A simple L-System:

initial: a
recursively apply these block replacement rules:
a -> [b a; a a] (these are 2x2 matrices)
b -> [b b; b a]

where a is represented as black, and b as white.
Decimated by 3 with 0 offset. This example repeats the replacements eight times. Also see Corner rotate inverse system.

wow, a really interesting pattern emerges when one zooms out / sizes down the image; i should try rendering this l-system sometime, thanks for the inspiration!
