Thanks for your comments, all appreciated and mostly interesting. I would have participated more but I, er, had to leave for a while... c1rcle wrote: "Slap the next person who says it's not art & tell them to wake up." I can't recommend that as a policy on this site. You're presented with the situation lmckenzie describes in post 57, and then end up having to leave for a while... ;-) For what it's worth (some people seemed to get the wrong end of the stick here) I think BigT's image was splendid, and a worthy winner.
