swab: add a perlin noise visualization
This maps a different Z-slice through the noise field to each color channel. The slices are moved up and down through the field over time, and the size of the area each color samples is tweaked a bit to make them less coherent with the noise field cells. It could be improved, but I think the output is already neat enough to be worth sharing.
