Digital artist Evan Bech creates these psychedelic visuals by using digital means to replicate a time-worn analog glitch technique: the feedback loop. A program that’s constantly taking screen grabs and generating new images goes haywire as Bech manually moves windows around, creating an effect that evokes both the old Solitaire win screen (thanks, Co.Design) and the Windows Media Player music visualizer. All in a pleasantly trippy way, of course. Check out another example below.
