Thanks Dave and Dan. No real credit for me here. All the work had been done for me and I just had to press the shutter.
No nothing about it Pete but I agree it is very clever. Lots to scan the eyes over if one had the patience. I'm nearly certain it was taken in Ekateringburg Russia, just the eastern side of the Urals. It was one of the places we got off and stayed in; Aisling (my eldest daughter) and I travelled from Beijing to Moscow on the Trans Siberian Train. Thanks for your interest Pete.
