Welcome to a new weekly feature: Tech Trumpet. Each week, I'll be attempting to create something vaguely resembling "music" using various gadgets and computers. This week, to ease things in gently, here's a track made up entirely of sounds from my favourite piece of communications software, Skype. I'll leave you to judge whether it's electronica, synth, ambient, all or none of the above. Hit the jump to play the music and find out what's coming next week...
