We twice presented a prototype installation that we call Rodots (aka Lo-fi Collaborative Agent Populations) at the Ontario Science Centre in Toronto, Canada, in May and July 2007. A broad spectrum of the public interacted with the projection, which began with a phase of “pixel-dust” gathering followed by a brief interlude in which a cluster of pixels followed one tagged participant, and finally transformation into a graphic that enabled the tagged interactant to participate in a herding task. The interactant-representative agent had to collaborate with two virtual agents to herd a target dot into a red circle. The sound for the prototype is based on a bank of oscillators that respond to the position of participants tracked by the overhead camera.
