Thingy 45 Degrees - Red to Cyan

This is a version of Thingy, where instead of slicing the RGB cube into 256 layers, it is instead sliced diagonally on the axis from red/black to cyan/white into 511 different layers. Resulting layers that don't fit fully at the right sides of their rows wrap around to the left side of the next row. Image Licence: Public Domain (CC0).
