Tchaikovsky's 1812 overture reconstructed from 1000 cellphones, 2000 text alerts (video)

We're suckers for a well done ad but this, this is simply amazing. Vodafone NZ's Symphonia features 1000 cellphones syncing 53 different ringtone alerts from 2000 sent messages to reconstruct Tchaikovsky's 1812 overture. We dare you to not be impressed. See how they did it after the break.
