Duh. Why this is cool: White-board clocks are among the oldest things on "the Internet".
Got a link to another one?

#62I love the way it writes, it has so much personality.
Yet if you watch the video, each time the "natural" looking numbers are almost identical.
I liked the erasing style. Bit clumsy like a toddler.

Chalk would still run out and need to be replaced. Some kind of sand drawing would be more of an infinite "ink".
Hilariously, a good way to do this with infinite "ink" would be to draw the letters on a touch screen with a stylus.
Or, just use one of the children's magnetic drawing board?

#65Using a home presence API (like Nest's), this thing could also abstain from updating the time until you were home or in the same room as it. That could dramatically reduce wear and tear.
Just hook up a human PIR to that thing. Only $4-5.

A kit would be nice for those without the necessary expertise or access to a 3D printer.
You don't need a 3d printer. Access to a laser cutter will suffice.
Not sure if you meant this as a joke (a laser cutter is probably harder to come by than a 3d printer). But back in my day for things like this we simply used a jig saw to cut out parts from wood or plastic. Anything more complex would need several pieces cut out and glued together.

#69This reminds me of a "plotclock" that I built almost a year ago. http://www.thingiverse.com/thing:248009
Just out of curiosity how is the ink usage, could it run for longer then a without replacing the pen or refiling the ink?
EDIT: Just saw the super interesting comment bellow linking to a reddit thread where it calculates the theoretical values of ink usage.
