Via Jonathan Turley, I came across this domino line made of 10,000 iPhone5s. It is pretty impressive. The split-second timing required to have elevators involved is amazing.
I have mixed feelings about such exercises. On the one hand, they clearly involve a great deal of imagination, a lot of work, and almost infinite patience, and you have to admire the dedication required to pull it off. But at the same time they seem such a waste of time. I can never see myself doing such a thing though I enjoy watching it unfold.
The big question though: How the hell did they get hold of 10,000 iPhones?
UPDATE: It turns out that the effect has been faked. Still pretty cool, though.
