Hey Downvoter, did you not get it or did you think it was not contributing? This is one of the most amazing little life patterns and I hoped that it had turned up, instead there are two far more complicated patterns that have much shorter runs.
Using larger grids and combining this with the famous HashLife algorithm to "compress Space and Time" (http://www.drdobbs.com/jvm/184406478) would be awesome!
Try it!
