I saw this lamp when i visited the ny moma over winter break. The user can take the included chisel and crack open the "egg" to reveal the light within. Different ways of chipping create different levels of illumination through varying porosity. The interactive light fixuture also doubles as an one-of-a-kind work of art. In other words, break me off a piece of that.
