Digital Sundial

Posted in digressions, Sundials of Note by Heidi

Wow: a sundial that displays the time, not by throwing a shadow on a set of lines, but in plainly readable digits. The dial functions from 8:00 to 5.55 hr, in 5 minute steps, with a smooth transition from one reading to the next. The sundial has been invented by Hans Scharstein and Werner Krotz-Vogel (Germany) and Daniel Scharstein (USA). More info.
