On the band Kraftwerk's web site, the page where they sell their merchandise is called Kling Klang. I like that term so much because it sounds like an old-fashioned cash register that I have christened my filthy lucre page with that monicker. I have a variety of items for sale, from holography laboratory equipment to proceedings from various conferences to stock image holograms to art image holograms to original art holograms by yours truly.
