From the 3rd to the 5th May in London some of the most creative graffit art could be seen at The Cans Festival. A disused tunnel was transformed into a gallery featuring many of today’s leading street artists (although most people would have gone to see the original Banksy creations). The artist Vhils produced some incredible portraits using paint and a drill to add a 3D effect to his artwork. If you missed it (like me) check out the photos on Flickr.
