Or, how to spend $1 million in just over 12 minutes (actually, about 3 1/2 days).
[CORRECTION: I previously had said $3 million, which is what I had heard on the streets. I've since been contacted by a representative of the SFMTA who assures me that the cost was in fact $1 million.]
This is a time-lapse video showing the replacement of the MUNI tracks in front of my house. Demolition began on the evening of Friday, October 8, and work continued around the clock until early in the morning of Tuesday, October 12. The MUNI folks were nice enough to distribute earplugs to those of us in the immediate vicinity.
This was shot using a Canon A590, with CHDK installed (a firmware replacement for Canon cameras that enables all sorts of additional features). An image was captured approximately every 15 seconds.
