WireWorld

WireWorld is a Turing-complete Cellular Automaton that can be used to simulate circuits and logic gates. You can try out the simulator here.

Here's a guide that walks through the process of building a wireworld computer that calculates primes, complete with logic gates, flip-flops, adders, read only memory and registers.

Rules

A wireworld is made up of four types of cell.

• Empty
• Wire
• Electron Head
• Electron Tail

After each tick of the simulation, the following rules are applied.

1. always stays

• always becomes
• always becomes
• If has 1 or 2 neighbours, it becomes
  • Otherwise it stays as
