This is a little late notice, but if you are in London and aren’t sure what to do tonight, how about wandering the city for art. In the same vein as Adam Neate’s street art give away, the art group Beautiful Crime is hosting their Valentine's Day MassARTcre. The basic idea is a massive drop off of canvases around central London, while people like you and me look up location clues via their twitter account. Some of the artwork that will be distributed can be seen here and here. Good luck and stay warm.
