In the code as it stands, simple integer math is used, I.e. results are truncated from their full real value. I had been considering widening the hour indicator to two pins, so that it could be distinguished from the minutes (seconds is easily distinguished because it moves faster). Dithering (or anti-aliasing I guess) the hour hand would be an interesting challenge. The likely downside is that it would be dimmer, although now I think about it that might also be an interesting way of providing a visual distinction between the hands.
