Quantum Corral (Coaster)

I have designed a replica of the standing wave that gets created in a quantum corral of 50 Fe atoms. It is also created to the size that it should work as a coaster or you can just use it as a decoration.

Note: Realistically the amplitude of the wave decreases as it distances away from the center, however I keep them all the same height so that it could be used as a coaster
