I've animated birdlike characters before, but none walked with birdlike legs. Okay, real birds don't wear glitter shoes. It drove me nuts trying to get it to cooperate. I closed dozens of botched jobs. It was ridiculous. Thomas Edison kept me going. Supposedly, when asked about failure he boasted ,"Why, I haven't failed, I've discovered 10000 ways not to make a lightbulb!". So each twitching, flopping or stroby bird that got deleted was one step closer to getting one that worked.
