Where you looking for a Conway’s Game Of Life simulator written in Go? Probably not, but here’s one anyway: https://github.com/nhoffmann/life. It started as a toy project (it still is), but evolved into something more than just implementing the Game of Life. It ended up to be a pattern viewer for every possible pattern from the Life like cellular automata.

Features:

• Supports all possible birth and death rules
• The board is infinite
• Load patterns from RLE files
• Magnification of the board
• Dragging the board to inspect certain areas

You can play around with it here: https://www.zentralmaschine.net/life/public/

I have some ideas on how to improve things. Mainly making the interface easier to navigate and improving the performance. For now this is fine though and I am happy to be one of those people that implemented a Game Of Life.

2020-04-11 Update: Sadly, news got out that John Conway has died. Even though Game of Life is apparently not the thing he wants to remembered for, I am thankful for his idea. Here is a video of John Conway talking about Game of Life: https://youtu.be/R9Plq-D1gEk
