Diffraction Anti-sundial

[Anselmo P�rez Serrada]

   I believe the best solution is the CD sundial or 'difraction
sundial'. You only need a faulty CD
and a transparent sticker to draw the lines of a 'spider dial'. See the
Compendium, Nr 3 Sept 1990.

   It works very well indeed.

Best regards,


Anselmo
