Eyeball Dome
The Eyeball dome is constructed with a 2x4 frame, 12 ft in diameter, and plywood skins inside and out sandwiching LED lights. The outside is painted with an inverse night-sky, and has constellations lit by the LEDs. Inside, the eyeballs are made from slumped glass, reverse-painted with oil paint, and back-lit with the LEDs that are controlled by an Arduino to dim and brighten on about a 30 second cycle. There are 15 different animal sounds, on two tracks and four speakers. It is designed to have one noise go on for every person who enters, and one turn off when a person exits. The floor is covered with astroturf and large astroturf pillows.
