is an autonomous roving device whose movements are determined by a collective of houseflies. Sensors detect the subtle activities of flies housed in a spherical chamber mounted to a roving device. The device's direction and velocity are determined by the movements and density of the flies. The device can move about a space in any direction at any time based on the swarm's input. The collective acts as the brain of the device causing it to travel throughout the space interacting with objects and people based on the flies orientation and predilections.
