And they have some wonderful properties. If you look at the hexagon, for instance, it's like an amoeba, which is constantly changing its own profile. You can just pull this out, this becomes a rectangle. You give it a push, this becomes a parallelogram. But this is very shaky. Look at the pentagon, for instance, pull this out -- it becomes a boat shape trapezium.
