Art of the Gable

I found out the following Saturday that this is Art, not Graffiti. Apparently it is done by tipping a pot of paint down the wall from the parapet and running along the roof with the pot as you are pouring. Then you get a brush and run that along the dripping paint. After that you do it again with a different coloured pot.

I think it works well but I'm a bit nervous about trying it at home.
