Check out this recent piece by artist Nemo Gould titled Zip Synch. The heads for the strange and endearing creatures are small zippered film canisters.
From Nemo Gould's web site:
The inspiration came from the little film canisters that form their heads. I had done this once before with the piece "Head Case #2". Recently I came across several more cases at a flea market and couldn’t resist making a chorus line of them.
In addition to the film canisters, the piece is made from sprockets, chain, gears, motor, LEDs, mirrored plastic, and wooden box.
