Zhe155 is a UK based artist whose "China Girls" stencil pieces have been making ugly urban landscapes across Europe a little prettier. David Bowie would be proud. You can see more of his work at Flickr.
I'm really digging these skateboarding stencils by Singapore street artist TR853-1. The skaters are creatively placed so they are ollieing gaps, jumping a set of stairs or performing a hand plant.
