Our main public area is The Big Dome, a 50' diameter dome with a white cover.  This used to be the ThunderDome.

Gerry's Video Art

360' video rig, with the idea to create a bullet-time dance cage.  There's a ring of usb cameras (320x240) feeding into one computer which will be connected to a projector.  One camera is displayed at a time, and the view switches from camera to camera (potentially with some blending), so it looks like you're rotating around the subject in the center.
