I came across a script by Fede-lasse and knew it would be perfect for making the "random lines" program that has been around since at least the early 1980s. When I was a kid I had seen it on a black and white TRS-80, Apple II, Commodore 64, etc.

An old version of Windows featured it as a screensaver, and then the classic arcade game Qix used it as the boss character in it's very fun for its day game.

I uploaded it as an example, so it should be posted soon. It took me about 2 hours to make, which is only because I'm a slow coder :). I was interested in the speed and quality difference between the standard 'draw_line' algorithm and the one Fede-lasse came up with. If you press the spacebar it will toggle between the two drawing methods. This nicely illustrates how jagged the standard mathematical way of calculating the distance between two points in space using single color pixels is.
