Two anonymous students, who go by "Dangerdust," get A's for the dope chalkboard illustrations they leave behind in a Columbus College of Art and Design classroom every week. Each one of their chalk creations is centered around a quote from a famous thinker or creative. Their elaborate sketches sort of resemble motivational posters and are rendered in vivid colors with designs and patterns so intricate, it's hard to believe they were done on blackboards.

Dangerdust has clearly put a lot of thought into these chalkboard works, for each piece pairs a quote with visuals that best typify the theme of the illustration. For a set of quotes from Steve Jobs, for example, the duo has matched it with the display of an old Macintosh desktop. Take a look at some of our favorites above, and click here to see the rest.
