This museum takes an irreverent look at art, while still honoring the visionaries who have created the wonders contained inside. From the moment you approach the repurposed brick buildings, topped with a wind-powered "WhirliGig" and emblazoned with the words "O Say Can You See," you know this won't be your usual art museum. Inside, a temporary exhibit winds through the first floor, up the stairs, and into the second-story galleries, all based on a single theme. Recent exhibitions have looked at all things round and the connection between human and machine. These shows of sculpture, painting, and mixed media accompany the permanent collection. All of it is created by people who without any artistic training felt compelled to draw, paint, or build a throne of bottle caps. Occasionally the art is troubling, while most exhibits are a joy for any age. The artists' stories are always a compelling part of each exhibition. In honor of the 2014 bicentennial of the Star Spangled Banner, local artists have created a colorful sidewalk painting alongside the museum. Mr. Rain's Fun House restaurant (443/524-7379; www.mrrainsfunhouse) and the Side Show Shop add to the fun.
