5.1 sound from a single source

A few days ago, some friends and I were talking about this device. Early in 2003, Pioneer will release the PDSP-1, a single source speaker system capable of producing discrete 5.1 channel surround sound audio. The device does not use psycho-acoustic techniques to simulate 5.1 channels. Instead, it actually bounces sound off of the ceiling and walls in order to direct the sound the proper locations in the room. [via Gizmodo]
