Highway Ramp for Light

Caption

Each individual "light switch" is constructed like a microscopic highway overpass. When the switch is off, the light passes straight through a lower channel (red lines). Turning the switch on lowers a tiny ramp, directing the light to an upper channel to make a right turn (blue lines). A second ramp lowers the light back down.
