In places some of the nearby plants are covered in a thick layer of ice where they have been splashed. Starlings are the main culprits in the 'splash it all over' scene as they don't mind how cold water is.
Most interesting, to me anyway, has been the formation of another little sculpture, once again hollow where the running water still flows.
Only a bit of video can show the effect:
On a technical note it is amazing how well modern methods can compress a video. The original clips as taken by the Lumix totalled 225MB but using a format called H264 this was reduced to under 20MB but still gave a good clear result. It certainly saves on upload time.
