I love changing drawing styles.
Confession: I have done this. The vending machine at work has motion sensors at the bottom of the drop so that if nothing falls down, you get your money back. With enough abuse, you can get 2 for 1 deals on particular items. Bags of chips will get snagged by other bags and there's just something wrong with the cookie dispenser. And yes, I have gotten 2 of an item I would never have purchased by itself.
