The variations on only two forms makes this interesting. There's the pentagonal fronts of the buildings, each slightly different, and the multiple ladders and steps, each different again.
Alan likes the handling of the sunlit white paint and so do I.
But there's another thing that interests me. I'm seeing the sunlit white in the image against the white of the web page. There's no doubt that the web page is objectively brighter, but nevertheless, the sunlit buildings seem brighter. It's is very curious, isn't it, that our perception works this way?
