Mechanics in nature.

There's a protein that's basically a tiny little mobile suite that literally walks along microtubules.

Some bacteria propel themselves with a literal electric motor.

Your ears are more something that belongs under the dashboard of a helicopter than something growing organically... they can literally detect an air-pressure change caused by a pin dropping on the other side of the room, by allowing that pressure to beat on a drum connected to a chain of bones that transmit pressure into a little snail that squirts little jets of fluid over a tiny little field of grass stuck to the inside of the snail shell, and depending on how much grass wiggles, it sends a jolt over to your brain as an interpretation of pitch. AND IT DOESN'T STOP THERE! Connected to that snail are three little hula-hoops made of bone, each oriented to a different plane, and also filled with tiny grass and fluid; and when you move your head along that specific plane, the tiny grass wiggles and that's how your brain knows which way you're moving / gives you a perception of balance.

There's a type of grasshopper with gears in its legs.

I love this shit.
