C82 is dedicated to the works of Nicholas Rougeux, including data art, visualization, and design.

"C82 was born from a desire to display the digital art I created and the hope of getting my name out there in the online world. Over time it evolved into a playground for personal experiments and a vehicle for voicing my opinion on art and the web."
