On Monday we checked out the Cans Festival on Leake St at the back of Waterloo Station where Banksy and another 60 artists, as well as members of the public, had left their mark and rather spiffing it was too! After queueing to get in for 30 mins or so we wandered round in a sea of people, a riot of colours and the fresh fumes of spray cans. I took so many pictures that I simply had to post three batches. So there.
Update: You'll be able to see the artworks in the tunnel for the next six months, so if you missed it or if you're planning a trip to London soon you'll be able to check it out for yourself!
