Er..that's what the guerilla artists of Open Doors would like you to do either by Twitter or via the comments section of their website. I last reported on Open Doors here, but to re-cap they describe them selves like this:
"Open Doors is a series of themed exhibitions throughout London that take inspiration from the galleries postcodes. The galleries are very kind people's homes and the artists are talented people excited by the opportunity to make relevant art by using their medium to document the lives of a local community".Can't see much wrong with that and they seem like interesting people, their current gallery is on Galloway Road W12. So give it a go and see what this excerise comes up with!
