It's not bad! Looks better in person than in pics. It's actually very neat to watch. I got this from Amazon for $18 shipped. Pleasantly surprised.

EDIT: apparently, this is supposed to have GLITTER in it. Either the glitter is dissolved, or Lava Lite's idea of glitter is different than mine. There is NO glitter in this lamp. There IS white "stuff" in there - looks like the same kinda stuff that's in snow globes.
