		Technical Summary
		Holographic Mylar Panels
		The walls, ceiling and floor of each room are made of reflective holographic mylar adhered to half inch foam core panels which are three feet by two feet in size. The panels are attached to wood paneling making up the sub-structure of the room using velcro material. When light hits this surface it is broken down into its component spectrum, causing rainbow colored reflections to scatter in multiple directions.
		Lasers
		Seven mixed gas (Argon/Krypton) ion lasers are used for this installation producing 10 watts each of visible light output. The output is a single beam, white in color. When dispersed by a prism, there are as many as thirteen distinct beams of different colors ranging from deep violet on the low end of the color spectrum up to bright red at the far end of the color spectrum. The lasers are placed inside custom-made optical projectors behind the holographic walls. There are seven complete laser projectors used in this installation. It is these optical projectors that house a series of mechanical devices, scanners, mirrors, beam splitters, prisms and electronics that splits the laser beam into dozens of separate beams, varying colors and scanned laser patterns.
		Studio Spot
		The Studio Spot is an “intelligent” theatrical moving light fixture. Two models of Studio Spots used in this exhibition incorporate a 250 and 575-watt metal halide discharge lamp, which produces light of continuous spectra similar to that of sunlight. With its moving head design, the light from this device is programmed using a computer designed for this system to move around at variable speeds, pan, tilt, spin, change color, intensity and alter patterns via gobos that render images and textures in an instant. There are total of 15 Studio Spot 250 units and 42 Studio Spot 575 installed in the exhibition.
		Cyberlight
		Similar to the Studio Spot but different in several ways, a Cyberlight is another, more sophisticated intelligent theatrical lighting instrument that houses a 1200 watt lamp and uses “moving mirror” technology that sends the light pattern in all directions. 23 of these units are utilized in this installation.
		ETC Source Four Par Lamps
		A series of these compact 575 watt tungsten halogen flood lights are set up along the perimeter of the space against the walls. This light source is based on incandescence of hot filament and the lamp emits a white light, but its color temperature is significantly lower (warmer) than that of a Studio Spot and Cyberlight. There are over 60 units in this exhibition.
		Strobe Lighting
		Out of all the lighting fixtures incorporated into the program, the xenon strobe units are the most intense. The units are placed along the foot of the walls lining each room. In the lighting program, the combined strobes emit over 40,000 watts of light in one quarter of a second. The intensity of the strobe lights is amplified with the holographic mylar and mirrored spinning cubes sending bright white light throughout the room. There are a total of 21 -1,000 watt fixtures, 50 - 3,000 watt strobes and four 25,000 watt strobes used in the space.
		Xenon Spot Lights
		In the main hallway at each end of the gallery are two opposing 7,000 watt Xenon Spot Lights. Typically used outdoors at special events, these units, also known as Sky Trackers, send intense white shafts of light down the corridor. Smaller 3,000 watt units are incorporated in Gallery 2 where the room is made up of highly reflective material similar to that of road signs.
		Fiber Optics
		State of the art fiber optics and intelligent, color changing fiber optic illuminators are incorporated into Gallery 7 whereby the fiber optics distributes light evenly within the interior and exterior of the reflective cube. There are a total of eight 150 watt illuminators and 200 feet of 1/4 inch fiber optic cable used in this space alone.
		Cubes/Motors
		Over 6,000 cubes of various sizes attached to gear motors and suspended with monofilament lines from the ceiling at different heights complete the installation. The variable speed motors allow for the cubes to spin at varying speeds and in clockwise/counterclockwise directions. The cubes are made of plastic mirror materials that allow for all lighting and laser effects to reflect off the cubes and radiate out into the entire space.
		Power Distribution
		Power requirements necessary to run the installation are two generators, each delivering 350kW of power at 480 volts. Special transformers break the power down to each location where each room has its own specific requirements.
		How It All Works
		Hiro Yamagata creates the laser and lighting effects in collaboration with a team of highly trained laser and lighting technicians and media programmers. Individual effects are programmed into the laser and lighting computer and stored for playback on a dedicated show control system designed by Alcorn McBride of Orlando, Florida. This allows for flawless, hands-off playback of the entire program and resets itself to begin all over again. The artist dictates movement, color, duration, speed, intensity and pattern. The entire program entails several weeks of planning, preparation, testing, installation and programming.
