I am going to show a installation that I found in RCA’s exhibition. this installation contains 2 parts. one is the air blower and a transparent ball. another part is light and shadow of the ball. the transparent ball is very light which can be fly by air blower. however the ball moves up and down slightly.there are only two circular lights on the wall. the shadow of the ball is limited by a square which is between the two lights. the power of wind make the ball fly. but also control it.

with the voice of air blower, the ball is moving slightly and never out of its orbit or fell on the wall. it’s a specific plan which never broke up. the moving ball represents destiny.
