New York artist Rosemarie Fiore has created a series of large scale paintings/”acrylic drawings” that are more or less giant Spirographs. She posted a couple videos explaining her unique process. [Modcult]

I connected a gas generator and air compressor to buckets of paint and secured them into the seats of a Scrambler amusement park ride. Once the ride was in motion, paint sprayed out of the benches onto vinyl tarps placed underneath. The result is a series of enormous hypocycloid designs which recorded the hidden patterns created by the ride as it turned.
