Now cellphones are not just for lighting up concerts and stadiums at night.

Recently stumbled across this cool video produced by Vodafone. 1,000 cellphones along with 2,000 text messages play Tchaikovsky’s 1812 overture in an innovative (yet disturbingly time-wasting) production.

Intrigued? There’s apparently a followup video that shows us how Vodafone orchestrated (pun intended) the whole thing in an Auckland, New Zealand studio.
