# Hyperbolic paraboloid

Can I get a perfectly symmetrical saddle-shaped pringles from the surface of a donut? If it is possible, what kind of torus, I mean if it would only be possible from a specific ratio of circles, or just any torus will do? Perfectly symmetrical here just means that you can flip the chips upside down (plus a quarter turn) and the result won't be any different from the original shape. I would appreciate any and all input about this shape, and please teach me the basics if what I'm asking here don't make any sense to you at all. I tried reading up from the net, but sometimes the language become a barrier, so a forum would be better for me to understand, with 2-way communication available.
