I recently bought a tiny tiny computer – the Raspberry Pi model B. Right now it’s running Pi Musicbox, and I use it as a streaming station. The Musicbox enables the Pi to serve as a remotely controlled Spotify-client and as a AirTunes-player. It’s very nice to not need your computer or phone to listen to music. Anyone can control the music, through a web based control interface, which also opens up for more interestingness.
I’ll probably experiment more with this!
