Whilst I don't have an appropriate PDA to run this on, this
animated windmill theme for Pocket PCs
caught my eye (though quite why you would want a power draining animation running your battery down all the time is beyond me).
The image looks to be of a Caribbean windmill - note the waving palm trees in the foreground, and the telltale porch out the back
to cover the sugar roller mill (the wind direction is pretty predictable in those parts!). However, the only workable mill I know
of in the Caribbean is
Morgan Lewis, Barbados, but its too open a view to be that - perhaps it's just a computer generated
animation, rather than film of any one particular mill, but it does claim to be in the "reality series".
I've been directed at another working wind powered Caribbean sugar mill, that of
. The island which is about 10 miles in
diameter once had 600 windmills, of which 73 remain, including the one restored working example. That would appear to be the
one featured in the animation. There is more information in French on the
