I hadn't seen anything on discourse about this so here is my take on Wireworld.
As the title says, Wireworld is a type of cellular automata. It resembles and can simulate some electronic (digital) circuits.
A little reference

A working applet can be found at

Also, for anyone interested; the code. All you need to make your own is to save a bitmap with your four favorite colors for space, wire, electron head, and electron tail.
