Here are a couple of websites showing work by creative recyclers, a.k.a as junk artists! Mostly metal bits though.

http://www.trotter.com.au/homepage/index2.html Well known Australian artist using mechanical parts. Lots of animals...
http://www.edouardmartinet.com/info.html A French guy, seems to use bicycle and kitchen appliance parts, wonderful animal sculptures.
http://www.lobue-art.com/home.html Australian I think, different sort of work, objects which look like old memorabilia, or historical artifacts.

I have bookmarked some sites of furniture from recycled stuff, which I'll post later.

Cheers!
