I found this mildly interesting: the "screenshots" in this article are made out of HTML elements.
Since the visual appearance matters here more than being searchable by "", drawing the shape in CSS would be more consistent: http://aamirshahzad.net/moon-with-css3/
EDIT: Pretend there's a moon in those quotes. HN strips some Unicode characters, including that one.
