Wobble Analglyph

south up image by yuri & the Atronominsk team

This image will probably cause seasickness in those with a faint disposition, but it is a delight. It is an animated - much too animated perhaps for some - gif alternating between two separate but registered images of Cleomedes. The offset of the images is due to changes in the position of topography following from the different librations at the times of the two images. The image does reveal elevation differences - a more traditional - and less jarring - way to detect them is a stereo pair requiring red-blue glasses, and it is interesting where the changes are strongest. For example, the floors of the deepest craters Cleomedes and Geminus oscillate from side to side, but for Cleo the oscillation seems to nearly stop about half way up the left wall - I would think the entire wall would seem to move. But I don't have stereo vision and can't compare the wobbly image with the real stereo view. Somebody tell me how well this works.

This LPOD was written on my iPad - more challenging than using the laptop. I still don't know how to deal with the images - I saved them on the web page before I left for this current trip to Birmingham, Alabama.

Technical Details
I can't figure out how to cut and paste so will fill in this when I get access to my laptop.Ditto for correcting Yuri's capitalization above.
