As most of you will know I've been posting the original image with virtually all of my recent entries. In this case though, as the transformation was slightly unusual, I've decided to hold off adding the original until you've had an opportunity to tell me a) what this is, and b) what additional post-production was done to the shot. What I will tell you is that it was shot during my journey from the UK to Bulgaria :)

Update: As Marcel has managed to identify the shot – it's one of the travelators at Manchester airport, warped in post – I've added the 'show the original' link. As you can see, the original is blue, but the perspective is slightly different in this version (courtesy of the warp tool) ;-)
