Anywhere But HERE! is a playful examination of the use of party photography as social currency. Participants use an assortment of props, costumes, and computer-aided special effects to fake being at an imaginary location.

For more pictures from the installation, check out the page on the Digital Situations site.

Here is a little taste of the openFrameworks application that we used to project the backgrounds. For the whole thing, head to the downloads page.
