My 3D-Design class really pushed me this last semester. This was our "audience" piece (and also modularity, 100+ items to make up a whole), my audience was doctors, and the subject recreation, showing a "I'd rather be fishing" theme. It's mounted to a white board using large fishing hooks and nails. It's assembled using fishing wire, many, many fishing hooks (possibly 200), two weights, and two little bobbers.
