LockWasher Design creates fantastic metal sculptures, mostly creatures, from found objects. The R2-D2 made from the Heineken Can attracted a lot of attention.
I chatted with the artist for a while. He's very friendly and told me a humorous story about cops in San Jose not letting him sell his sculptures that look like ray guns. He also told me another story about the occasional electronic engineer that sees his work and identifies the decades-old object he used. In one case, it was a microphone from the 1950s about which the engineering waxed nostalgic.
