Don't Get Dizzy

Peter Rosen asked earlier in the week if I could make an animated gif of Ptolemaeus' floor, with the lighting rotating around in azimuth 360 degrees. I have managed to come up with this with the Sun from 10 degree azimuth increments at 1 degree sun elevation. It is made using the highest resolution DEM I could find, it says 1024 whereas the other full disk one is 64 (not really sure what this means either). But it is better as I compared the two. It is just a segment of the Moon, so there is a bit of clipping of the righthand side that goes over the meridian. I hope this shows you what you wanted, Peter.
