Melinda,

The geometric lights out puzzle is what I suggested earlier in this thread… Later I tried playing the Cube and the icosahedron version of "Lights out" on a piece of paper. "Clicking" a vertex flip the state of adjacent edges. They were pretty trivial to solve. Maybe if we increase the number of edges that each "click" affects, the puzzle becomes harder.

The real deal here in 120-cell is pretty hard to illustrate… Some configurations http://en.wikipedia.org/wiki/Configuration_(geometry) may make great Lights out puzzles.
