For 40 years James Turrell has been creating skyspaces that harness and enhance the experience of perceiving light. He has just completed his 73rd skyspace at Houston's Rice University. Titled Twilight Epiphany, the pyramid-like experiential work of art provides two light shows each day – one at sunrise and one at sunset – in conjunction with the arc of the sun. Visitors gaze up at the 72-by-72-foot white roof which offers a view of the sky through a 14 x 14 foot square opening. LED lights on the ceiling change colours as the sun rises and sets providing a wash of oranges, greens, pinks and blues, impacting on the colour of the sky as seen by visitors.
