The Mandala Gesture Xtreme (GX) System was created in 1996 by Toronto based computer entertainment company, the Vivid Group. Mandala is able to track the player’s movements without having to wear, touch or hold anything. Sharkbait was one of a number of games/virtual environments created for this computer vision based virtual reality system. It allows the user to engage in virtual contact sea animals and to seek out treasure; users must collect stars as they sink and avoid eels and sharks that swim by.
It was installed in Taiwan at the Taichung Ocean Aquarium as part of an interactive exhibit, and overall, seems to be used in conjunction with scientific and educational exhibits.
Thanks to Lisa Shapiro for pointing this one out.
