This ad for Vodafone New Zeland is an impressive technical feat. They loaded up 1000 cell phones with ringtones for single instruments, and then built a system to send text messages to them in the correct order, to get them to perform a portion of Tchaikovsky’s 1812 overture. Considering the amount of delay that I usually notice when sending messages, I was pretty surprised that they claim to have performed this over their regular cell network. [via gizmodo]
