Like his book, both pieces are named The Time Machine. One is a 16mm film loop that projects huge images of two lilies on a large screen. One lily is a real flower, the other an animation of a clay model that looks deceptively real. Through time-lapse photography, one flower blooms while the other withers, then the sequence reverses. Continuous looping mimics nature's birth-death cycle.
Time is both speeded up and reversed.
The juxtaposition of real and artificial flowers describes a tension between nature and artifice, which is intrinsic to film and video generally. Time flies, and life pulses with an eternal rhythm. You probably already have concluded that these are simple ideas that have been expressed in similar ways countless times by other artists. True enough, but the film-loop version makes a vivid visual statement. Yonemoto has a talent for dramatic staging, as we see in two other pieces.
