The orbital tilt appears to be about 31 degrees and either the phase with respect to the Earth’s equinoxes changes or the curves move up and down between slides (I’m still working on that, but it's making my head hurt). This doesn’t fit with anything in our solar system, so it’s clearly from the Hitchhikers Guide. DaveP
