Awwwthanks Adrian. That's well put; I'm the same I feel: it's a bit like treading on a nail which is peeking out of an otherwise perfect parque floor: it's surprising that it's there...and then one starts looking around for more and treading more carefully!
D' ya know...I'm thinking of redoing the image as it's just too, er, "something" for me. One of those "hmm" moments..!
