Nope, that isn't a motion tween - that's actually the Drexel Shaft getting knocked down by explosives!
A bunch of us met at 6am this past Sunday to watch the demolition of the infamous Shaft, a building that has long embodied the administrative experience at Drexel University, our Alma Mater.
Back in college I made a cartoon about it for Tim's site, drexelshaft.com.
We got front row seats on the roof of the Cira Center parking garage, right across the train tracks (see yellow arrow). Some police tried to kick us off the roof because it was considered "unsafe" but they gave up on the existing crowd and just stopped letting new people come up. It was pretty damn epic.
