“All Eyes On You” by Britzpetermann are bunch of varied sized eyes that follow the passers-by. The team used a high quality projector and semi-matt foil to project the eyes on the window. They are rendered by a WebGL frontend using a shader sphere effect. The detection is performed by OpenFrameworks and the Kinect.
An Arduino controlled servo motor, pushing a button on the projector remote, is turning the installation on at 4pm and off at 11pm.
