Ehhh... it's not that impressive is it? I think it's worth remembering that you can get extremely complex behaviour out of conways game of life [0] which is as much of a swarm as this is, just with an unfathomably huge difference in the number of states any one part can be in. Any random smattering of cells in GoL is going to create a few gliders despite that difference in complexity.
