The center of the spherical room consists of a large 16th Century telescope used mostly for navigation on seafaring vessels. When approaching it the telescope lights, inviting us to look through its eyepiece where we can gaze at the Sistine Chapel paintings of the Heavens. In the CAVE, the gaze is controlled by the movement of the tracked user's head.
The planets that make up the solar system rotate around the telescope, hung from curved rods. The sound motif is a short excerpt from Wagner's Siegfried .
