Re: O.m.a.c.
Rucka went for traditional Greek myth and not popular myth. In traditional myth, no one could "avoid" looking at Medusa without some other implement. So if you tried to face her with your eyes closed, you couldn't and you'd still become stone.
From what I understand, what happened is Wonderwoman wore a blindfold that got torn off. Wonderwoman--knowing what would happen quickly tore her own eyes out so that she can continue fighting medusa.
I haven't read the comic, but heard about it and am anxiously awaiting the TPB. The TPB on Rucka's Wonderwoman run have shown a really awesome comic.
It really is a must read for his approach to the character.
