From the men responsible for Dina Martina's killer videos comes this bimonthly showcase of found-video delights, artfully assembled around a theme and projected onto the big screen for four mind-bending hours. Tonight's theme: subliminal messages, from song-and-dance propaganda to Christian freak-outs over backward masking and beyond. Stay for an hour or four—Collide- O-Scope's "low-investment/high-return video" pays off for as long as you want to pay attention. (Plus, free popcorn and Red Vines!) (Re-bar, 1114 Howell St, 233-9873. 7 pm, $4, 21+.)
