These don't seem to be getting very much attention, but they are pretty freaking cool pieces of artwork. I think maybe the reason they aren't more popular and are so hard to find is that people don't know what to call them exactly. I think their really called Rainbow Vision, but I noticed most websites have changed the name to Sand Art or Sand Picture because Rainbow Vision sounds gay. The maker is from Austria or something, so I don't think he realizes that Rainbow has a homosexual connotation here in the U.S.
