Some people like biking. Others enjoy drawing. Those who hop on Joseph L Griffiths' "Drawing Machine #1 (To Your Hearts Content)" get to partake in the most bizarre mash-up of the two the world's ever seen.
Griffiths' bike has a modified front wheel that draws large circles on a canvas in front of it with colored Sharpies. Its handlebars are attached to blocks of wood that create another set of markings when the handlebars are turned. It all results in a bike-made cacophony of color.
