Share 'A homemade glitter lamp?'

Hi all! Did you notice that there is a lot of information at different sites about homemade lava lamps, but none about homemade glitter lamps? I think that glitter lamps use much simpler chemistry than lava lamps, which is much easier to reproduce at home. But what chemistry exactly do they use? Maybe just water and glitter? Or some kind of oil and glitter? Can anyone tell me? Thanks in advance.
