it's the creation of a north carolina farmer named vollis simpson. >> he was 76 years old when he made93 and still making whirligigs. and he said, "i had a lot of junk, and i had to do something with it." >> it's a moving monument to recycling, made from cut-up street signs, parts from cars and bikes, and other strange things. what's really cool is that the more you look, the more you see. >> people love it. it got baltimore's most beloved piece of public sculpture. >> well, i can see why people liked it. you want to go in at number one? >> absolutely. just turn right around, carly. i think this is "b" for bling for baltimore. >> this entire wall is a mosaic of broken mirrors and glass. and not just any glass. >> the blue glass is known as baltimore glass all around the world because bromo-seltzer and noxzema were made here for over 100 years. >> but to get the full effect, you have to see the museum from a distance. no doubt, it's unlike any other building you've ever seen. the outside is as much a work of art as any of the works displayed in its three buildings, and just as unique. s
