Hundreds of Oregon State University students took over the Valley Library on Thursday, October 1st. (via the Oregon State University Admissions Blog)
It was a successful flashmob, although I really think that OSU (Oklahoma State University) and UNC (University of North Carolina) have set the bar for successful university flashmobs:
OSU flashmob in the student union:
UNC flashmob in the library:
Honorable mention to the UK (University of Kentucky) and CofC (College of Charleston) flashmobs:
Update: Please note that I do not endorse, support or volunteer for the OSU flashmob. Also note that Facebook was the staging area for the flashmob event.
