This reminds me of a "plotclock" that I built almost a year ago.

The writing on this one is much nicer! Add selective erase so only one character is (usually) ever erased and you've got yourself a very neat novelty clock.

I feel really bad for the little guy. It looks like he's incessantly unsatisfied with his work so he has to erase everything.

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.
