It hasn't been done already as far as I know, so I decided to make a version of Day & Night with multiple states. This version has 16, but it can easily be extended to any number. Although, I don't know why you would need more than 16.

It works as follows:
- The central cell counts how many neighbors have a different state than its own.
- If the number is 3, 6, 7, or 8, it changes to the state represented by the most of those neighbors.
- If there's a tie, it keeps its current state.

Watch out if you're starting with a random grid of multiple states; it runs really slowly. By the way, in case you don't know about it, I'm using random-fill.py from the Golly Scripts Database to fill grids with an equal distribution.
