This Artwork exploits a phenomenon that is a combination of persistence of vision, phi phenomenon and beta movement: a dense screen will appear transparent in movement, but opaque when still (eg. looking out the window of a moving train, you can see buildings through the trees, but if the train stops you will only see trees).

The Spinning Helmet mounts a densely perforated metal cylinder around the head so it can be spun from near-opaque stillness to near-transparent speed.  As the cylinder spins faster, the aesthetic experience should also be fascinating for those around, as the head of the user appears through the metal surface and then fades again as the spinning slows.
