Rhythm Apparatus For the Overhead Projector: a Metaphorical Device
The rhythm apparatus for the overhead projector is a robotic device that can be used to demonstrate core concepts of the theory of embodied cognition. At the same time, it is also an instrument for audiovisual performances. Combining the communication of scientific insight with amusement and entertainment, it stands in the tradition of phil- osophical toys. Such a device is introduced here and used to illustrate, in a step-by-step manner, principles of embodied cognition: emergence and the interplay of brain, body and environment.
