This is just one of the many amazing works by Derek Hugger:
Colibri is a wooden kinetic sculpture that simulates the motion of a hummingbird in flight. Every element of motion has been completely mechanized, from the beating wings to the flaring tail. Intricate systems of linkages and cams bring the sculpture to life with a continuous flow of meticulously timed articulations. As each mechanism has been linked to the next, Colibri cycles through its complete range of motions by the simple turn of a crank.
