Love it or hate it, the Michael-Lee Chin Crystal at the Royal Ontario Museum truly is a marvelous feat in contemporary architecture, and it's changed the way many Torontonians think about design in this city.

This timelapse video, consisting of over 4 years worth of photographs, is quite simple awesome. It shows one image taken every day at 1pm throughout the construction phase, and near the end, it shows one still taken every ten minutes during the building's opening week.

The details are captivating. The hundreds of school buses parked outside day after day, the large tree going from green to red to bare as the seasons go by, and finally the formation of the outer shell and the stream of people into the crystal make this an amazing depiction of a long, complicated process.

(Kudos to The Watcher on Tribe for pointing this video out)
