Talk about feedback mechanisms! Paul Cocksedge’s Kiss installation in Milan invites couples to kiss under a giant sprig of mistletoe. When two people touch the central leaves of the mistletoe branch a chain reaction occurs, sending a trickle of light up to the giant canopy overhead a central plaza. A small human gesture creates a spectacular illuminated reaction.

You should really see it through the video clips on Cocksedge Studio’s site, right here.
