Digital Sky Lanterns at the Taiwan Pavilion

Flying lanterns are a folk custom in Taiwan, where they are launched during the Lunar New Year holidays to pray for good fortune, happiness and peace.

Here at the Taiwan Pavilion, visitors view a short film on Taiwan in the Sphere theater, which provides a 720-degree viewing experience. Visitors then can "light" digital lanterns after choosing prayers on touchscreens. The "lanterns" go up the sides of the Sphere; images of the words on the moving lanterns also may be projected onto glass curtain walls in the pavilion.
