I saw them in the recent Tron movie and had seen them in a video somewhere that I cannot manage to find any more. The object flips between triangles and square shapes and I think may be named after a scientist or similar.http://img833.imageshack.us/img833/7686 ... called.jpg
To make it worse - I'm not sure these are actually the items I am thinking of.
Sorry for the vagueness of my description. In the video I saw someone manipulated the shape to change it from looking like a rectangular formation of square blocks that then split into triangular pieces.
Many thanks for any and all advice given!
