I’ve been completely lusting after something like a Sonos system that lets me play whatever music I want in any room in the house, so I can send audio from my computer to (for example) the living room speakers. Sonos (which seems like the only really decent system out there) costs hundreds of dollars, maybe thousands depending on your needs, so there wasn’t much chance I’d actually buy one.

Turns out I can do everything I need with a $25 application: http://rogueamoeba.com/airfoil/

This is totally cool as hell. I took a half-broken old iphone and made it the receiver for the living room speakers. I can also send from my computer to every other computer on the network, no problem. So for a party, it’s easy to make any computer be controlling music that plays in every room in the house (using some cheap thrift store speakers etc as needed). It’s also equally easy for Celene and I to dynamically split the house into a couple of zones, one where she’s hearing the music she’s playing, and one where I hear what I want.

Note that that $25 covers installation on all your computers. One-time fee 🙂
