Part of a bumper video for TedX Sydney 2012 using crowd recording to create particle could interactions. The video used an XBox Kinect and was rendered live. The concept illustrated the fact that during an event like TED there is the potential of making strong connections between the people there. This video work visualizes these connections from real crowd interactions.
