Went down to Cardiff Bay last night and took a shot of the lock gates on the Barrage. I seem to be getting yellow circles all over the image!
Are these Circles of Confusion? The urban equivalent of Crop Circles?
Now look carefully! They're painted on the metalwork/concrete! Cool or what? The top one at the very back is an enormous line painted on the seawall (actually, when I first saw it I wondered why they'd painted an enormous yellow swoosh on the wall!)
This 2 shot pano taken with my mobile but I'll definitely be back when the light's better
