Very Nice in deed. Visually appealing as well. Wrote a cellular automation algo with unrealscript back in UDK using the based on this.

Your work rekindled my interest in Conway’s Game of Life. Found inspiration that may be applicable for GOLEM Entity Construction. However, I will not be using cellular automation for procedural level generation in favor of the Depth First Search Algo:

My recommendation, if you intend to add multiplayer or reuse a specific procedurally generated level, make use of Random Streams/Seed for random number generation. Keep us posted and good luck.
