But is it art?

The art class had a day out - in the morning at the Le Corbusier exhibition at the Barbican Art Gallery, then the afternoon looking around the East End galleries (most seemed to be between shows) and making our way to the Whitechapel Gallery for the tail end of the afternoon.

But the galleries weren't the only place you could have thought-provoking visual experiences. OK these might be random occurrences - or they might be deliberate interventions (by people with art-school credentials...) - you be the judge ...
