It has 5 fold symmetry. It's broadly a pentagonal shape (viewed from above) made up of the same piece repeated five times. It's actually rather simple and beautiful (to my eyes). I'd not have been surprised if the model they ran spat out some ridiculous random-looking shape that happens to fit some local minima. As it is, it's a fairly reasonable-looking twisted ribbon like shape.
