Kai Krause was born 1957 in Dortmund. He came to California in 1976 with two friends. He worked as a musician for Disney Sound Effects; the soundtrack for “Star Trek: The Movie” was created on his synthesizers. In fact Kai won a Clio Award for his sound effects in a Star Wars radio spot. Emerson, Lake & Powell bought sound systems from him and he is still working with Peter Gabriel today in order to fulfill his vision of visualized music as 3D sculptures.

He was running a forum for several years on AOL: Kai’s Power Tips & Tricks. He gave people tips and little pieces of code on line, simply because they shared his passion for computer graphics. This became an extensive and valuable collection of practical information how to get special effects with Adobe Photoshop.

Many of the filters in KPT3 like KPT Texture Explorer, KPT Spheroid Designer and KPT Convolver use a rectangular area that fits on a 14″ monitor. All other elements get blacked out – no menu bar, no Photoshop image window and no desktop. The user experience is really like coming into a room with a special suited environment for one specific task.

Krause’s software was simultaneously the most interesting and the most frustrating user interface I’ve ever experienced. Thanks to @Navesink for the link.
