Slime Moulds are So Cool

I read this fantastic piece on Slime Moulds, whom it appears, may be as old as the earth’s ecosystem. They are amazing things that can solve mazes:

As well as predict the best place to build a road network! To me, Slime Moulds are so fascinating in that they represent a mid-point between a single celled organism and multicellular organism. They are also fascinating because they are a network of semi-autonomous cells that co-operate non-hierarchically to find food, reproduce etc.
