Surreal Machine China

Here you see one of those surreal machines, creating sky from water.
This image was merged from a photo of mine and a great HDR sky capture from mescon – thanks for your CC licence!
The machine is part of the Tinguely Fountain in Basel, Switzerland which was built from metal junk.
Machine part captured with a Canon G9. Worked the photo with GIMP.
