This drawing turtle was produced in response to a brief in which we were asked to create a "Rhythm Machine". I decided to build a machine that created rhythm through movement rather than through sound.
The turtle is connected to a computer, and can be controlled directly using the keyboard (Arrow Keys). The computer records the turtle's movements and these can then be "played back" in various sequences, in order to produce rhythmic patterns. Various "Playback Modes" are available including: Mirror, Reverse and Decay.
Some of the resulting drawings are shown below:
