Concrete

Perhaps it's the nature of pouring concrete, or union jobs, but the middle of this time lapse is pretty boring. Sorry about that. The beginning is fun enough; and the end, with the inch-worm workers and the vacuum-like concrete massager, is cool, too.

Please note the right 1/3 of the image is slightly affected by the reflection of the building fa├žade on the window.
