Start with a simple idea, add a slide projector and a turntable, and you have the pleasantly surprising Nicolas Moulin installation, "Pole."
Now at the Gallery Koyanagi, a high-class Ginza art space that's avant-garde at heart, "Pole" is a low-tech piece that combines strangely ambiguous pictures of building exteriors with low-end audio feedback to create a weird and unsettling atmosphere. It is one of the most engaging works of art showing in Tokyo right now.
Granted, thing have been slow recently, but an otherwise boring Ginza gallery promenade last Saturday took a turn for the better when I stopped in at the Koyanagi, having first noticed the unending waves of feedback floating out through the door and onto Chuo-dori.
