ZigZag on Spiral

3D Zigzag walk of the RGB color cube projected on a 2D Spiral curve starting at (2048, 2048). Generated by calculating the distance of each coordinate pair (x, y) from the starting point, and then decoding the RGB channels as the coordinates corresponding to the calculated distance on the 3D ZigZag curve. The ZigZag curve is quite simple: think of a zigzagging curve in 2D starting at the top and wiggling throught the second dimension and now expand to the third dimension by thinking of a plane wiggling from top to bottom.
