Way back a long time ago I had the idea to make a sundial using a mathematically designed surface according to the analemma of the Sun's track across the sky. Now I'm reviving that idea, making a new set of images. There are only two, so far, but stay tuned for more. Click on the thumbnails to see a larger image. There are also movies of these sundials.

Here's the old one that I did around 1994.


The movies of the 1994 dial don't work anymore, but I made some new movies of the new dials.
