House on the Rock is architect Alex Jordan’s collection of a bunch of random things - big and small - that you can see in a span of 30 minutes or 3 hours (depending on how much of the house you're willing to look through). If you're up in the Wisconsin area, you just have to make a stop at House on the Rock. I promise that it's not an attraction you'll soon forget. (If you need a "real" reason to head up in the area, Frank Lloyd Wright's Taliesin is also in Spring Green.)
