Here's another idea. It seems that there are about fifteen threads that've floated around Delphi about how the game pieces have been triangles and circles and squares. How about just blowing all of 'em out of the water once and for all with three different game pieces on the field, one of each form (a four-sided pyramid, a cylinder, a cube) that must be assembled using reasonably strong magnets inside each piece. You then get the awesomeness of stacking without the ridiculous ease of knocking over.
