I got these (and a few more) sent in an email from my friend. I can't give you the credits for the design then, but feel free to point it out to me. I have to say I'm pretty inspired by these, especially by the one made out of "Don't Walk" sign! My ex flatmate used to collect road signs, sometimes I got them as presents. I think I still have a huge cirle blue sign somewhere in his garage, so maybe I could come up with a use for it....
