Camera Obscurae at the Print Center

The Print Center, near Rittenhouse Square in Philadelphia, features one of the more unique installations in recent memory: Richard Torchia has turned the second floor galleries into camera obscurae, using pinholes and lenses to give the viewer an eerie, upside down look at the neighborhood. The Print Center is devoted to presenting printed art, but these images are fleeting. The camera obscurae (literally dark rooms) project their images in real time instead of capturing them on film or paper.
The installation is up until February 25, but if you go tomorrow (Saturday) you may get to see snow falling up in your field of vision.
