Hi. If you've watched HBO's "In Treatment" series, you've seen what I'm looking for: a lava wave machine. (At least, that's what I think it's called.) It's a clear cylinder (maybe 15" long) mounted horizontally an arched base. When you turn it on, the cylinder rocks like a see-saw, and the blue goo inside simulates ocean waves. There's a photo example at
. Somebody said such a gizmo was once made by Lava Simplex, but I'm not sure. Can anybody help me locate one -- preferably without the dolphin and surfer figures that come in some of the newer models? Thanks.
