Cut & Paste Digital Design Tournament

Eight graphic design experts compete to see who can best visually interpret a theme in a 15-minute round. The best part? Each computer screen is projected so the audience can follow the creation from start to finish. The event–presented by Cut & Paste–will feature MC Ove and DJ sets from Kid Robot’s Chad Phillips.

(Note: The after party is at Home Sweet Home, 131 Chrystie St.)
