Here's a picture of a brooch I made recently for a competition (
Ars Ornata - Inside Out), but it also counts towards my degree work (I'm in 2nd year and loving it!). It's a composite skeleton, essentially, and the pin and catch are formed by the hands (one of which is a bat's arm and the other is sort of human).

He's all bundled up, a little like a bronze age burial - that was the idea, anyway! He's made from mild steel wire (about 1.5 and0.7mm thick), with one silver rivet and one finger made from stainless wire to form the pin, and was spot welded together. At the end of making him I blackened him with heat and then sprayed him with furniture polish to try and stop rusting.
