Street art is most often borne of the spray can, so why not make make art from the cans themselves?
That's exactly what this anonymous artist has been up to around Shoreditch and Soho (and perhaps elsewhere... but these are the only places we've seen it so far).
The installations are formed from decorated food and drink cans, with the occasional aerosol thrown in for good measure. It's certainly a novel way to recycle.
We can't find any information about the artist online, so please do leave further information and examples in the comments.
