Yesterday I bought one of those Apple AirTunes thingies (wifi internet, wireless printing and wireless streaming music all in one) and some Harman Kardon SoundSticks, weird glass bulbs which glow blue in the dark over by my bookshelves. When you plug the AirTunes unit and the sound system together, you can "throw" sound wirelessly from iTunes across the room, or the whole flat. You can have DJ soundsystem clashes with your partner, also beaming in iTunes from her iBook. You become a perma-DJ, and wear large, silly, happy donkey ears like the ones I'm shaking about right now to, well, the sound of hair being clipped.
Alejandra and Aeron's lovely ambient work made me want to listen to my own soundscapes of Porto, recorded earlier this year. But how to do that, when the mp3 plays back in Safari and only iTunes can transmit wirelessly to the SoundSticks? The answer is Airfoil, which allows you to send audio from any application to AirTunes.
