Does anyone know the best sources of information on Lava Lamps and/or Glitter Lamps? Is there a definitive book or expert/author? Where do you all get your information? Are there catalogs or pamphlets from various makers? I am mostly interested in vintage lamps. I saw the one posting for the "Cocktail shakers, lava lamp" book and am waiting for Bryin's coffee table book. Anyone have any suggestions (aside from reading every page of this web site)?
