Have you been out today?

So I just leave the room for a moment with Radio 3's Late Junction playing on the radio and a high res scan going on and when I come back I think for a moment that my scanner's busted because it's making a horrible grinding sort of noise. But no, all is well: the noise is, in fact, some of your standard Late Junction fare (Transylvanian throat singing or something of that ilk) and my scanner is making no more noise than a contented whirr. Phew.
