I agree there's some pretty naff ones. Richard and Judy as a formation is just the pits. But if you go a bit deeper into their site eg. http://www.circlemakers.org/totc2002.html there are some superb creations. True art surely?
I have to ask, what is it that makes the unattributable ones so much better? I'd ask you to post one up but no doubt Pete G will say he lent them a rope, so I won't. I'm just interested to know what there is about them.
