2009 Apr 9, 8:56Someone implemented the Ironic Sans artificial sundial clock concept! "Last year David Friedman published on his blog Ironic Sans an interesting design concept for something that he called The
Bulbdial Clock. That's like a sundial, but with better resolution-- not just an hour hand, but a minute and second hand as well, each given as a shadow from moving artificial light sources (bulbs).
We've recently put together a working bulbdial clock, with an implementation somewhat different from that of the original concept."
