Freezing the Moment on YouTube

Various performers, artists, and technologists have experimented with transforming our experiences of physical spaces and our experiences with others in those physical spaces.  From PacManhattan (the analog of PacMan) to less orchestrated flash mobs, it is hard to fully describe in words the experience as a participant or as the audience. Luckily there are now some YouTube videos that better share the situations.  (Below is Frozen Grand Central - crowd simultaneously freezing in one place for 5 minutes and the reaction of those who normally zoom by.)
