One of the big dilemmas posed by a piece of art is where to hang it. That's not the case with an exhibition going up Friday in the gallery space at the Tattoo Factory on the North Side. "Paintings for You to Poop On!" is a collection of art made on toilet seats and lids, including a devil telling you to "Leave the Seat Up," a Jesus telling you to put it down and an Elvis surrounded by pills (view the art below).

You could call this category of art a movement, but then you'd be getting dangerously close to the bathroom humor used by many of the artists. Call it, instead, accessible. "We wanted to offer the gallery as an avenue for people to have a good time and enjoy art, rather than going to a stuffy, hoity-toity, wine-sipping opening," said Beth Cisco, an artist at Tattoo Factory and one of the organizers.

With her husband, Phil, also a tattoo artist, Cisco is doing her piece as a tribute to the late, legendarily transgressive punk singer GG Allin, known for incorporating toilet-related materials in his live shows. "I'm not sure what this category of art is called: lowbrow?" said Mitch O'Connell, a professional Chicago artist who helped Cisco organize the show. "It's basically a genre of art influenced by things like pop art, wacky, fun stuff and the surreal."

O'Connell put out a call to artists, and the submissions have been trickling in. He figures there'll be about 40 works ready Friday, all of them priced from $100 to $400.

"I like art that can be used," said O'Connell. "You cannot interact more personally than with your own fine art toilet seat."
