Neon green and fuchsia lines, like laser beams, define the planes of the room, giving you the impression of being inside a three-dimensional blueprint drawn by an architect on hallucinogens. The virtual space extends 40 feet below the floor you are walking on, so you may have the sensation at certain points that your next step will plummet you into the abyss. Look up to find that the room continues upward for many stories. The 2-D screen grab you can see on this page will give you a hint of what the installation looks like but, not unlike a photograph of a sunset, it fails to capture the sensory marvel of the experience.
