This item is to showcase the wedge acoustic panel option.
The central idea is not random, but completely deterministic wedges' alignment.
Despite the determinism of the structure, the pattern is non-periodic and self-similar (fractal type), looks like a random one.

Interesting properties:

1. Any of two adjasent wedges are rotated 90 degrees to each other.
2. Compared to random alignment, patten is more uniform.
3. The spectrum is close to white noise.
