A fisheye angle photo inside a large white and silver room that appears to be several stories high. Orange beams, cross-beams and a ladder are inside, as well as a large silver-colored rectangular prism with four pairs of light green X-cross beams. It has open sides. At the far end, an open garage door. One person uses an arm to lean forward on the prism structure.
