No Smoking (please).

Artist Daniel Eatock has an art and social exercise going on where he's asked readers to submit their own vectorized take on the No Smoking logo (usually a cigarette crossed out by a red circle and stripe). All designs can be downloaded now and used wherever you like and when he reaches 100 designs (he's not far off), he's going to make a poster. You may even see a couple designs done by my good self.
