I went skiing with a buddy this past weekend, where by "skiing" I actually mean "learned to ski by falling down half the mountain."

Ski bindings are interesting. They are simultaneously a safety release that detach the boot before you hurt your legs (skis are levers and your legs don't want the force multiplier) and a modulator for all the input forces you control the skis with.
|Super-well thought out mechanisms that consider biomechanics of falling|
The rear binding has two especially interesting features. The first is a spring-loaded snow brake. When the boot heel is securely clamped in the binding, the heel keeps this snow brake folded up. But the moment heel pressure is released, the brake arms pop out and dig into the snow. So now, your skis won't fly down the slope without you! Additionally, the brakes raise the slippery surface of the skis off the snow - very helpful for when you're trying to reattach your boot while on a slope.
