  • Patent number: 4726503
    Abstract: A participartory device for producing artwork which includes a canvas or other suitable art medium mounted between a plurality of rotatable support posts which extend perpendicularly upward from a base. The rotation of one support post drives the canvas causing a lateral movement of the canvas. The device includes a drive mechanism which, in the preferred embodiment, is a bicycle-like apparatus permanently attached to the base. The rear or drive wheel of the bicycle-like device engages a plate member which extends radially outward from one support post so that pedaling the bicycle-like apparatus causes rotational movement of the support post and lateral movement of the canvas. The individual pedaling the bicycle-like device can apply paint or other drawing media to the moving canvas thereby creating a design on the canvas.
