Kyaraben - an elaborate bento meant to look like characters from anime, manga, or games. Flowers, scenery, animals, people, buildings, and all manner of other things may also be recreated in bento form. Also related is oekakiben (picture bento).
Mikasa bento. I can't even. It looks like ham, but I think that if I make it, it'll be turkey or chicken. Annoyingly, though, I clicked the link, THE INSTRUCTIONS ARE IN JAPANESE. Which is super cool. But also extremely annoying. Because I haven't learned Japanese yet.
