This is the Flash prototype of the"When Doves Cry" interactive installation. The above image is projected onto a wall. A blob tracker recoginzes the x,y,z and area coordinates of a passerby and feeds these into the Flash file. The end result is that as a person walks past the projection, a dove follows him/her. As a second person walks past, a second dove follows. As the doves near one another, the olive branch appears.

In order to simulate this action, move dove1 with the arrow keys. Move dove2 with 1,2,3,4 keys.
