Keep in mind this first example is of a mannequin. Apparently, it obeys the laws of physics as it falls through an infinite sky of spheres. If it gets stuck, you can click and drag it—even if it’s not stuck, that’s kind of fun. Jenn thinks it’s too weird to watch, so your mileage may vary.

The second example isn’t quite as neat, but it’s still worth a quick look. It’s a “liquid-man” who just follows your mouse pointer around the window.
