Here is hoping this year is a great one for all!
I ran across this time-lapse video of the Church Street and 30th Street MUNI track replacement in San Francisco. This was captured every 15 seconds for 3 1/2 days and took over 18,500 images to piece this together into a 12 minute video. Quite impressive in the production of the video, but impressive also in watching all the work that got done in tearing up the track and putting down new track, then rebuilding the road all in 3.5 days. Amazing!
Cheers!
