When you search eBay for a DSLR Rig, you'll find a ton of these 'Movie Kit Shoulder Mounts'. I received this one a while back from eBay to demo, but never got around to doing anything with it. I personally am not into these transforming rigs, but I know a few people have sent in comments and videos showing use of them. Here's a quick demo of some of the configurations they can bend into. Again, not my cup of tea, but might be something entertaining for someone out there. Prices have definitely dropped since they first appears, and you find them on the web (click here).
