Transit planner Paul Supawanich took this slightly hypnotic time-lapse video of commuter shuttle use of the 21-Hayes stop at Hayes and Steiner.
This video, which Supawanich says was taken on "Thursday March 6, 2014 between roughly 6:15 AM and 9:15 AM during the morning peak," is intended "to observe how commuter shuttles and Muni operates at this stop."
An unintended side effect? Sent this SFist staffer into a pleasantly fugue(ish) state. See what we mean (sorry, we wish it were embeddable, but it is not) here.
Paul's video found in Noe Valley SF's link roundup, which always has such good stuff!
