Bank Holiday. Nothing happens. Well, something happens: as a result of a recent birthday and a very perceptive woman I am now the very proud owner of a binary wristwatch. Press a button and it lights up the time as a couple of rows of tiny red LEDs -- each lit up for a one, or extinguished for a zero. Thus 12:45 is rendered 1010 101101: entirely mysterious to anyone who didn't spend a lot of their youth building digital circuits for fun, and thus entirely compelling to anyone who did.
That would be me, then.
