Gabriel Dishaw calls himself an up-cycler or "junk artist." Basically, what he does is he takes small components from various old, dismantled mechanical devices, and creates something wonderful out of them. Up top is his newest work, something he calls the Red Stag Vader.
In fact, he's done several Vaders:
This one's the aptly named Steampunk Vader.
And here's "Darth Money," named so presumably due to how shiny it is.
There's a lot more to check out over at Dishaw's personal website, including mechanized skulls, humanoids, animals, even more Darth Vaders and, interestingly enough, shoes. Those can't be too comfortable to wear.
