Earlier this year, Julian O'Shea released a short video detailing a
peculiarity about the Shrine of Remembrance in Melbourne, "How Daylight
Savings Broke this $24 Million Building":

The shrine, originally dedicated in 1934 to honor those who served in World
War I, was designed with a small aperture in the roof.  Each Remembrance
Day (11 November) at 11:00am local time, the position of the sun would be
perfectly aligned to shine through the aperture, allowing the light of its
rays to fall upon an inscribed stone inside, thus commemorating the hour of
the Armistice.

The problem?  Several decades later, in 1971, Victoria adopted DST, but of
course the aperture had been tuned to the position of the sun at 11:00am
AEST.  So what do you do to preserve this meaningful element of an annual
ceremony with important dignitaries, when it's effectively been moved an
hour earlier to 11:00am AEDT instead?

The answer involves a clever system of mirrors.  (And the general public
still gets to witness the light following its true path an hour later!)


Since this is quite a grand physical representation of how we interact with
our timekeeping, I've added this to tz-art.html, as well as a few fixups to
unclosed HTML tags nearby.
