These have always fascinated me. The hyperbolic paraboloid is a surface curved in two directions, but composed entirely of straight lines. The finished surface is very strong and has sometimes been used for roofs. I made this one of toothpicks and hot glue as a sort of proof of concept, and it is quite strong. If you press it flat and let go, it springs back into shape quite vigorously.
