Kinetic art is art that depends on motion for its effect. That motion can be machine, wind, solar, pressure, force, and a hundreds of other means of movement. I get very excited when I see this (Kinetics) used in interesting ways such as this Old Spice commercial. It seems to be a flash video edited to seem like his muscles are powering the instruments but the theory is sound. It is very funny and creatively unique to its market, plus the interactive add on increases its intrigue .
