German artist Niklas Roy created "Instant Art Career", an "interactive installation which turns anyone into a successful artist," for the Katowice Street Art Festival. Staged in an abandoned store in Katowice, Poland, the project displayed a painting machine in the shop's window. Any passersby could use this machine to contribute strokes of paint to a growing work of art. The finished painting was the result of everyone's collective effort. The machine was operated by ropes that controlled the movement of brushes on a canvas. Each artist received credit and compensation for his or her creative input. Works were auctioned off during the festival, and participants split earned commissions.
