Watching the Sprinkler Work

@Bhavin: Thanks for commenting. The garden has a very tricky surface; its has slopes and straight surfaces, heaps and mounds, so I wouldn't know which is level in this picture. The trunk of the tree is also crooked. I think I held the camera level and I myself was level. You raised a very good point, however, I did not realize how dynamic ;-) the garden surface was.
