Ninja street artist strikes again.

There's been lots of these appearing around Glasgow, and I love them. The guy (or girl!) draws up a load of pictures and pastes them around on unused buildings and other nooks and crannies in the city centre. There's been quite a lot of zombie-esque hands and things, but my favourite was a fantastic picture of Franz Kafka (since been ripped off the wall).

This one is on one of the fire exit doors at my work. Not one of the best ones in all honesty, but I think the paint/bleeding nose effect is brilliant.
