The image was encoded into 13 binary images/sprites (png transparent or visible) using a Blender (blender.org) node setup. The cursor senses whether it can touch each sprite, if it can, it adds to the shade or hue variables... Let me know if you would like more info on this. this is what this picture looks like, done perfectly, with auto pen instead of human ability to draw straight and for it to work online i would need to change the script that sais "if x = 240 set x to -240" to "if x > 240 st x to -240" weird, eh?
