The most appealing shape to me is a pyramid, mainly because of how it has been used throughout history to build some of the greatest structures.

THE RHOMBICOSIDODECADEDRON why?.. It has 20 triangle, 30 squares, 12 pentagonal shapes, 60 vertices and 120 edges

Wackiest one I can think of is a Möbius Strip. The wackiest way I've seen it used or mentioned is in an explanation of how we should move our hips in a style of Karate. I think it influenced the creation of mathematical topology as a field of study - properties of shapes. Rhombicosidodecahedron is another good one... There's a Big Bang Theory moment where it's mentioned.

i love minecraft and i love unusual shapes so im going to choose a minecraft circle they are so pretty
