I saw this in a group show titled I may be some time... at James Nicholson. It was my favorite piece, and made me very annoyed that I missed his solo show at the gallery. Here is an installation shot from that show:

This was in a group show at Hudson Franklin titled Best Played with a Straight Face. According to the gallery, the artist photographs different buildings, digitally manipulates them, has color copies produced and then wheat pastes them to the wall to achieve the pattern she wants.
