An analogue bitmap clock.

Digital clocks are nice for telling exactly what time it is, but, unlike
an analogue clock, they don't give a spatial representation of time.
They don't show where time is coming from or going to.

On the other hand, a bitmap representation of a mechanical clock doesn't
tell time very accurately if the bitmap is very small. And curves and
oblique lines don't look very nice in a small, low-resolution bitmap.

So, I decided to come up with something different, to come up with an
analogue clock that isn't tied to the design of the mechanical clock,
but instead uses the natural properties of bitmaps: straight lines and
rectangles.
