This is the sort of thing...

This is the sort of thing ... that a real geek does for fun.  After reading this, I just wish I'd thought of the problem first :)

Think about this for a moment before you go read that post.  Consider the numbers 24 and 50, written in Roman numerals:

24: XXIV
50: L

Fifty is, of course, a much larger number than twenty-four in the usual way we think about numbers' “sizes”.  But notice that twenty-four is wider (on the screen) than fifty when written in Roman numerals.  That's the observation that provoked the puzzle in the linked article.

Now go read it :)
