Kinetic sculptures are simply breathtaking.

Drawing green engineering and art together, they give a glimpse at what great beauty can emerge from an unconstrained mind.

Perhaps the world will overflow with these spectacles in a time of better education and less strife.

Here are five fantastic videos of the very best work.

5. Solar Horse

Apart from the crank shaft, motor, and solar panel, the entire body is made from paper. Bonus: the video is set to an appropriate Goldfrapp song.

4. Rhinoceros

Although it weighs two tons, this steel and cloth structure will walk forward with a very smooth gait if the wind is strong enough.

3. Extremely Creepy Tree

As the wind blows across these metal tubes, the air inside vibrates — creating a tremendously eerie sound. It howls like a banshee and overlooks Pendle Hill, the site of a bloody witch trial.

2. Da Vinci Automobile

Built from plans drawn by Lionardo Da Vinci in 1495, this vehicle is powered by springs.

1. BMW Tribute to Theo Jansen

"The walls between art and engineering exist only in our minds," says Jensen as the video ends.
