The latest in a series of un-curated art exhibitions — which since 1999 has been providing a showcase for any artist with a hammer and a nail — has set up shop in downtown Frederick this year, with work by nearly 300 visual artists in such media as painting, drawing, sculpture, photography, video and craft. Read my review of the show, but before you hit the road, take a look some of the works that caught my eye.

Alexandra Arzt is one of Artomatic’s standouts. Her series of photographs documenting human-animal interactions includes this surreal portrait of Ohio veterinarian Melanie Butera with Dillie, a deer that lives in Butera’s home. Dillie has her own bedroom. (Alexandra Arzt)
