"walking on two balls" in 1995 was a way to feel the precarious balance of the first steps, or better, and to make the viewers aware of the complexity of what looks like the very simple act of walking. "the third eye" (1996), is an ingenious device to dismount the mechanism of vision, turning obvious the hidden, unconscious process that results in the act of seeing. with "flying machine" (1995-1996), and the "sisyphus chair" (1998), the myths of greece are revisited by ho to show how absurd are man’s attempts to go beyond the physical limits of his body. a series of works, “gravity hoop” in 1997, and “an evolutionary body” in 2000, illustrate in a very original way the scientific theories that explain the human body as a machine, constrained by the laws of the universe.
