I used to use unix computers in the 90's for building GIS systems. There used to be a screen saver which consited of a maze that filled the screen. Then the computer would logically solve the maze with a shaded path, a lighter shade for the wrong decisions and a darker shade for the correct decisions, and eventually showing the completed solution.
I would love to see this screen saver again, and even get it for my windows computer.
Does anyone remember it?
