With the help of electronics many things can be done with sundials also, but if they all are of practical use I doubt. But an electronic dial I like very much is an equatorial sundial for blind children. It is realized in 1991 in Zeist, Netherlands, and a picture of it is on my Internet site. (see below) Follow the link Pictures of Sundials in The Netherlands, page 1 number 10. The children have to rotate the equatorial disk until a beep is heard. In braille they can read the time. Happy dialing, Fer. -- Fer J. de Vries [EMAIL PROTECTED] http://www.iaehv.nl/users/ferdv/ lat. 51:30 N long. 5:30 E
