How does a glass cube drive a nail into the wall for hanging up a picture?
If used as a hammer it is just another hammer (and an ineffective one at that because it is going to slide off the nail and cause you injury or shatter and cause you injury).
It is an actual solution, you can get a nail in with a cube, it probably won't break 'till the fourth or fifth nail. (I have used glass bottles to drive nails.)
