Randy Sargent is shooting a panoramic zoomable time lapse (aka time lapse gigapan) all day Thursday December 8 from the sidewalk of McArdle Roadway 100 lateral feet from the top
(location is at center of this map)
The panorama will include most of this view (click link)
He plans to be at that location shooting picures every second or two from 5:30am until 11pm!
If you're in the area, you could drop by and say hi. Or if you bike/walk along the Mon Wharf or some other location downtown visible from the top of McArdle Roadway, you'll be in the video! Wear bright colors!
Here's a simple time lapse of the Paddle-at-the-Point event last year, shot with a single camera. Thursday's time lapse will use four cameras shooting in unison.
(I posted this same message to the bike-pgh bboard http://bike-pgh.org/bbpress/topic/appear-in-a-time-lapse-video-of-downtown-on-thu-128#post-90344 to publicize it some).
