Night Penguin
I find that penguins always make an interesting subject -- charming, expressing, and instantly recognizable. This is the first time I have tried making a trading card or anything like an embedded origami image, so a penguin seemed the least forbidding place to start. Black on black and feet on ice. I'm not completely happy with the beak, but on the whole it turned out much better than I had expected. I hope it gives you a chuckle. (No diagrams yet, I'm afraid, because I'm just squeaking the image in at the last moment...)
