Here’s a fun little web app you can try out next time you’ve got a bunch of friends with smartphones in one place: JamBells.
Developed by Pointless Corp. during a 48-hour hackathon, JamBells turns your phone into a handbell. Start a choir with your friends and play one of the songs in the database like “Jingle Bells” or “Deck the Halls,” or use Freestyle mode to set each phone to a particular note and jam away. (Or if you sadly don’t have any friends to play with, you can use Freestyle mode to change the notes as you play—but it’s really not quite as much fun.)
Just visit JamBells on your mobile phone or tablet, and start ringing!
