If you open Flash, but don't open a document, the Size field is greyed out and displays "--- x ---" (when you open a movie, it will say "550 x 400 pixels"). The alternating on-off pattern that is used to grey the field out catches the whole upper half of the x though, and nothing of the lower half, which makes the whole thing look like the sleeping skull beneath the full field:

very blank

By the way, when does Flash get bones support? :)
