Buggy Barn has a really great one called "Live Loud," that's in their book, "Crazy or Not." You can add wheels on the snowboards and make them into skateboards. If you've never done a Buggy Barn quilt, it's quite the crazy experience, and I think everyone should do it at least once. Here's the only picture I could find.
