Kuvaputki is a multi-angle DVD by Embryoroom produced and directed by Edward Quist and co-produced by Derek Gruen aka Del Marquis, with music by Pan Sonic, the Finnish experimental electronic music duo consisting of Mika Vainio and Ilpo Väisänen. The film is "a hyper-real multi-angle DVD environment. Pan sonic, Mika Vainio and Ilpo Väisänen, are immersed in the imagery of the cathode which seems to live and infect their physicality over the course of three parallel films as they merge with their own extreme sound and into Quist's sinister vision."
