Default Human-powered sundial

Analemmatic Sundial

To find the time, a user simply steps into the sundial and stands on the current date shown in the scale in the middle.

Before clicking the link I thought "human-powered" as in a human had to spin the Earth, or push the sun chariot across the sky (depending upon your beliefs).

Thanks, learnt something interesting today!

very interactive for kids etc (operating and designing), the elliptical shape is clever.

apparently our Queen had one built for her Golden Jubilee.

(and there are henges in Canada: it's funny what intrigues people) ;-)

I attended the dedication of a similar sundial six years ago. It has fallen into disrepair, unfortunately.

I tried stepping into the sundial toseek talks about--and my shadow covered everything ID4 style.

Have to lose weight...

Last month, I checked up on it. It has been "repaired" by totally replacing the tiles that had been vandalized--leaving no evidence of the analemma!
