Eye of Cthulhu
You mean something like Kai's Tidy Wires?I'd like it if the blue and green wires were offset so that they would still be visible when placed on top of each other. (IE. if blue was nudged up to the left and green nudged down to the right.)
They work alright, but I can only imagine displaying the different wire colours in this fashion only getting increasingly difficult the more wire colours are added to the game.
