This kind of evangelizing sounds terrifying to me. I'm expecting more of these "whimsical" "fun" UI elements all done in the service of some poorly defined ideal of capital-D Design! The capital D is important.

Please, just stay away from my car accelerator.

While I'm not a huge fan of this checkbox, it is very clearly delineated in it's purpose. It's not design for design's sake, it serves one very specific purpose: To reward the user by giving them a (hopefully) satisfying interaction.

I don't see how you would think someone would try that with something as essential and utilitarian as a car accelerator.
