Unintended engineering.

Motor protein traversing a microtubule

Kinesin is a motor protein found in eukaryotic cells that helps transport cargo during critical cellular functions such as mitosis and meiosis. This animation depicts the proposed "hand-over-hand" walking mechanism by which the protein traverses a microtubule while carrying a cargo vesicle. The seesaw motion is caused by conformational changes during the binding and hydrolysis of the high-energy molecule adenosine triphosphate (ATP). Because microtubules are polar, motor proteins are only capable of traveling in a specific direction. Most kinesins move from the center of the cell towards the periphery.

In 1976 (yes, 1976), I heard my professor, one Don Norman, say pretty much the same thing.
