In St George skate park, at the far end from the car park, is a tombstone of a skate ramp, looking more like the monolith in 2001: a Space Odyssey than a piece of skating architecture. This is a favourite spot for some artists in Bristol, and recently it was the turn of 3Dom to decorate this wall.

I think the story here is putting urban civilisation under the microscope, but to what end I am not so sure. The microscope has been brilliantly observed and painted well and reminds me of the days when I used to do some real science rather than whatever it is I do these days.

This is a simple and striking piece that is brilliantly suited to the wall it has been sprayed on and offers us another aspect of this fabulous artist’s talents. I feared that with the sun behind the wall I wouldn’t get any decent pictures, but I think they turned out ok.
