Prague's Beautiful Astronomical Clock

This clock shows:

Modern time (24 hours, set on Central European Time)
Ancient Bohemian Time (24 hours from sunset every day, so changes day by day)
Unequal Hours (when the day and night were divided into 12 each, meaning the length changes day by day, and is different from day to night)
Position of sun and moon in sky.
How much day / night to expect today, with sunrise and sunset readable.
Phase of the moon.
The calendar dial shows the day of the month and year, and which zodiac sign is current.

And every hour, animated statues of the apostles come out.
