Investigating the Astronomical Clock of Prague

For use on Mathematica 4.0 promotional materials, Wolfram Research created a sample notebook briefly sketching the geometry behind the Orloj, an astronomical clock, which since the year 1410, has tracked the motion of the sun and moon in the sky over Prague. This article will describe the clock in more detail, including a description of the mathematical model behind it.

(If you don't have a copy of Mathematica, you can view the notebook using Mathematica Player.)
