Ever wondered just exactly what a worm hole looks like? I guess I must read too much Sci-fi but that's what came into my head when I looked at the finished image.
It's actually derived from yesterday's image of the York railway station roof with it's added reflection and then the whole thing rotated on its axis. It shows it's good to read your comments as the suggestion was made on yesterday's posting - thanks Dave.
Perhaps we should do one of those psychological tests and ask the question - look into the picture and tell me what you see?
