The work Coriolis relies on the misconception known as coriolis; the idea that water whilst draining, turns in different directions dependent on whether sited in the southern or northern hemisphere.
Existing in material form as a dubplate recording of water draining in the northern hemisphere, hence anti-clockwise, the turntable, playing the dubplate clockwise, effectively eliminates the recording. Dubplates have very limited durability they begin to loose the sound quality after 30 or so plays and are completely eliminated after approx 1000. What remains, a token almost of the artwork, is the empty vinyl disc. Equator coinage, maybe.
The work is available for purchase as a limited edition at Campbell Works gallery www.campbellworks.org.
