Datamancer has two of his wonderful Steampunk Keyboards up for sale on eBay.
First, the warm copper "Baron of Cyprus". Truly lovely, a work of art.
Second, it's dangerous (I know, it's a keyboard, but this one looks like it would grab your fingers and leave them mangled if it found you trashing science fiction with it), it's made of engine parts (hex nuts for keys!), it's The Industrial.
Lots more pictures of both over at the eBay posts.
We also have a peek into Datamancer's workshop.
