As usual Suck UK have produced something to make me smile. The Grime Writer – a pen that creates graffiti by cleaning. No ink in this pen, you simply fill it with cleaning solution and write away – on grime.

As they say “Much more socially acceptable than real graffiti and (more importantly) a lot less illegal – Grime Writer helps you leave your mark wherever you find muck. Use responsibly to help promote the phenomenon of negative graffiti, and brilliantly combine the crime of defacing a bridge with the community service time cleaning it up again afterwards, into one harmless, helpful, creative act. ”
