Falls Under the Heading: is there anything that can't be recreated with Legos?

YouTube user sumthinelse5790's utterly brilliant Lego prosthetic arm uses electric motors and extensive pneumatics to almost fully recreate the full range of motion of a real human arm, hand, and fingers. The Lego prosthetic is unfortunately not a practical replacement for the real thing. Although it's adept at gripping and holding various objects, it's only strong enough to lift a couple of pounds at most. And even sped up to twice the speed in parts of this video, it moves very, very slowly.

As said by the creator of the project: The main purpose of this project was to accurately mimic the full range of motion of a normal human arm and hand. The secondary goal was to maximize speed and power, yet maintain a consistent ratio between the two for demonstration purposes. It is important to note that it was designed as an above elbow prosthesis, and the yellow shoulder is only meant to act as a static model. The amount of weight it can lift is limited to the shape of the object and orientation of the wrist and elbow, but it can't do much with more than a couple pounds. The controller is a rudimentary cluster of switches and joysticks. A 4-motor air compressor with pressure-regulation was made of Legos, but for the demonstration I simply used hand pumps. This is a model prosthetic arm made entirely of Legos.

-hand movements and wrist abduction/adduction are Lego pneumatics
-wrist pronation/supination, wrist flexion/extension, and elbow flexion/extension are Lego motors (Power Functions)

I got this video as a Klout Perk .... just not sure what to say

To save you 3 mins of your life, its just one big advert for heart attacks ... done in a somewhat unrealistic comical way which makes it look fun, because everyone wants to have a heart attack, right?
This video is unlisted. Only those with the link can see it.

Just released shot of Enceladus and Saturn's Rings

A crescent +Enceladus appears with +Saturn's rings in this +Cassini–Huygens spacecraft view of the moon.

The famed jets of water ice emanating from the south polar region of the moon are faintly visible here. They appear as a small white blur below the dark south pole, down and to the right of the illuminated part of the moon's surface in the image. The image's contrast was enhanced to increase the visibility of the jets. See PIA11688 to learn more about the jets.

Lit terrain seen here is on the trailing hemisphere of Enceladus (313 miles, 504 kilometers across). North on Enceladus is up.

This view looks toward the northern, sunlit side of the rings from just above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 4, 2012. The view was obtained at a distance of approximately 181,000 miles (291,000 kilometers) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 136 degrees. Image scale is 1 mile (2 kilometers) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
