This morning, I was gifted an unusual stone. It is a block of Ulexite, which is known in some circles as the TV Stone due to the odd fiber optic properties of the stone. To see the effects, shine light through the stone.

Also, for fun with cats, shine a laser light through it and move the stone to create rings of laser light.
