Okay, even if you've never seen Evangelion in your life, you must watch this video. (Compare with this one if necessary.) I don't know how they did it, but that's a masterpiece. And Man-Rei is hot. :3

What's that? You want strawberry more genderbending? Here. Have some Melancholy of Haruki Suzumiya. (more pics here, partial light novel translation)

...Have I mentioned that I love genderswap? 'Cause I don't think I have.

EDIT: Well, I didn't think I'd find a Code Geass one so quickly...
