The Gömböc – cool and expensive
So the Gömböc is basically a shape with one point of equilibrium only, like a turtle shell, which will attempt to right itself anytime it is not on this point. Because of the unique shaping, moving to a point of equilibrium is actually fun to watch because it appears the object is expending a great deal of energy in the process.
Unfortunately for this very cool shape, its coolness is being exploited for cash. The “Official Gömböc store” is selling them for upwards of $750.00 (for Brass) and as low as $250 (for Aluminum). This puts it far out of the price range for curious dads like me who just want to show their kids something cool and could care less for the expensive Plexiglas/Alumium/Brass models.
Still, the idea is intoxicating and I should probably find the dimensions and make one myself out of steel/plasma cutter/welder and grinder.
