Ooops, that turned into a long revision break . . . .

About lunchtime I decided to take a break from my revision for an hour or so and have a mess around with Ableton Live (Music production software).  I've had it a while but never got round to installing it.  Turns out it's rate good fun and massivley addicting making (or in my case attempting to make) music.  An hour turned into 4 in the end and so the above track is the sum of my revision . . . . . . . . . . I wonder if any of it comes up in the exam???
