I was just working on some pictures for my other blog when I came across this shot which I took in a local church.  At the time I wondered what this mark on the wall was.  After some thought, my guess is that a candle or two has left some soot on the wall.  I’m not an artist myself but it seems to me there’s potential for an art project based on candle soot – I’m particularly taken by the graduated greys – almost looks as if something is trying to get out of the wall (too many late night horror films!)
