The Washington Post has been doing this Peeps® Diorama contest for six years, but this is only the second one I've seen (the first was in 2009). I took these pictures yesterday at Artomatic in Crystal City, VA. The Peeps are on the ninth floor; my wife's exhibit is on the fourth – I still haven't seen most of the other exhibits yet, just those two floors and parts of a couple of others. Click on the above picture for a link to the WaPo article; click on some of the pictures below to see alternate pictures of the same diorama (from a different angle, or close-up on details).
The next few pictures were just more Peeps-related art in the general vicinity.
