Justin Hopkins, who makes music and visual art under the name RareBit, created this series of drawings using only Micron pens, regular 8 1/2" x 11" computer paper, and a photocopier. He calls the series "Give Up The Headache," and with each image he explores a different relationship between the texture and color of his background and the static image of a brainy-looking skull. Hopkins calls the series an "experiment in Xerox and image layering" and we like the idea that some level of chance was incoporated to make such intricate images. By the way, that skull is actually somewhat of a recurring image in RareBit's work. 

In addition to his drawings and music as RareBit, Hopkins also moonlights as a sound designer.
