Larry Niven wrote about Flash Crowd based
on teleportation. The Internet has allowed people to do performance art in public and record for all of us the warping of innocent bystanders as to what is reality.
To me flash crowd = flash mob , so I credit Larry Niven with predicting an accurate social trend, people do this sort of thing, because the technology allows them to do it and derive pleasure for the "art" they created, temporary in real time, but stored on a web server for a long time.
Here we have the Antwerp Central Station being turned into a performance space.
