Thanks! Now it's time to try to understand it ;)

By the way, is it just me or is there a glitch in the middle of the image
(where the two boxes meet)? I see it especially in the lower triangle, the
stem of the P, and it's worse with increased effect_depth.

Another note, I see these things more easily with a lower number of
"strips" (a wider repeating pattern), otherwise my eyes tend to lock at a
too wide separation and I see double objecs or strange shapes. Changing
number_of_strips to 3 was nicer.
