Menger sponge

A Menger Sponge is a shape made out of cubes that looks like a sponge. It starts out as one big cube and then certain parts are cut out to make smaller cubes with holes in them. The process is repeated over and over again to make smaller and smaller cubes with even more holes in them until it looks like a sponge. It might also look a little bit like a honeycomb. It's a very fun shape to look at!
