For individuals that don't have the patience to hold a paintbrush, the Joseph Griffiths 'Drawing Machine #1' is the ideal drawing mechanism.

This is a stationary bicycle that uses the cyclist's pedaling motions to draw over a canvas. This could be the perfect installation for an artist's gym so that they remain productive even when honing their physical appearance. The handlebars are even used to draw, so when the user turns them side to side the drawings will be affected.

The pieces are entirely arbitrary so each drawing will be different. By the end of every pedal session a new masterpiece will be born making this an extremely inventive design that could give birth to new forms of artistic achievement. It can get tiresome hunched over a canvas with markers and a brush, so giving one's feet some work could make painting a much more appealing hobby.
