About a year ago, I was frustrated by the fact that I couldn’t beat the song Jordan on Expert difficulty in the video game Guitar Hero II.  One thing led to another and I ultimately hacked my Guitar Hero controller to “record” songs (what it records is the button presses and strums) in practice mode – at half speed – and then play them back at full speed.  Alonna made a youtube video showing it in action.

So that’s the kind of thing I do in my free time…  I have a slightly more detailed description of it here.
