I know the definition of an artist. My flatmate Rob (someone who actually has a semi-plausible claim to be one), happily confirmed this for me.

They have too much time on their hands.

I managed to get quite ill a week ago and after my temperature came down from 38 to something approaching normality I got decidedly bored with leaving my room (incidentally, based on a Swedish open-plan prison cell) on average twice a day, either for air or food. Hence I'm messing with the camera on my mac as I have sod all else to keep me occupied.
