Inspired by a Defcon talk given by computer security expert Mikko Hyppönen, artist Ace Volkov’s “Viroids” series took 63 of the actual computer viruses from history covered by Hyppönen and, based only on their names, gave them psychedelic sci-fi character designs that feel like one of the background characters in the bar from Tron: Legacy. It’s equal parts gorgeous art challenge and handy rundown through the history of computer viruses. You can see more of Valko’s work on his Behance page.
