With spindly legs that look like an upturned spider, this experimental kinetic artwork by Random International relies on the viewer to watch from just the right perspective to reveal a hidden secret. Each of the 15 ‘arms’ is tipped with white LEDs that collectively move to mimic the motions of a walking human figure. Titled Study for Fifteen Points, the piece was created to examine the “minimal amount of information that is actually necessary for the animated form to be recognized as human.”
