Tilt

Left leans the element four degrees anticlockwise and Right three degrees clockwise. Lean neighbours opposite ways, as the stickers on the brochure heroes do. Hover either one to see it straighten. The lean is a resting angle rather than a loop, so it stays under reduced motion too.

Put it on anything that has no lean of its own: a photo, a video card, a sticker or a terminal window, like this one from the Tech home. koala-mockup and koala-mockup-device take a tilt attribute instead, which sets the same angle. Notifications never lean; they sit level, as a phone draws them.
