Three out of six surfaces of the cube are made of flexible membrane (foil mirror) with air tank and a compressor connected to it and the other three mirrors are semi transparent spy-glass. By inflating or deflating the air tank, the membrane turns convex or concave, deforming the reflections.
The steppers are far too slow to write the time in under a minute so I delay it for a couple of mins between each draw. Mostly to give the very hot motors a while to cool off and to give the etch a sketch a break!
DNA Lounge update, wherein that was the best $5 I've ever spent.

@textfiles You know what Facebook doesn't do? Make amazing technology do anything but anger-hump your semi-private information. Forever. @warren ellis Cut to: Oculus Rift offices: "We glued an iPad to a diving mask and BOOM two billion dollars. THAT's our fucking TED Talk." @Chris_ Randall "Take this astonishing quiz to find out which immersive environment you are!!!"
We're done here.

The new quadruped, called the Glaucus, walks using only two input lines. It has hollow interior chambers that interdigitate with one another. When either of these chambers is pressurized it deforms and bends the structure of the robot. This bending produces the walking motion. It is similar to how a salamander walks, by balancing itself on one pair of legs diagonal from one another while moving the opposite pair forward.
Crabster CR200 onland walking without skin:
The world's largest and deepest underwater-walking robot, the 1,400-pound Crabster CR200, was designed to scuttle along the seafloor like a monstrous crustacean. Its possible vocations include scientific explorer, commercial surveyor, and treasure hunter. In fast currents too dangerous for scuba divers, it steadies itself on six legs by putting its head down, raising its rear, and facing the flow head-on. It has 11 cameras, including an acoustic one to see through cloudy, turbulent waters. Engineers at the Korea Institute of Ocean Science and Technology held Crabster's first underwater trial last summer. This spring, they plan to test it at maximum depth (656 feet) and then head to the Yellow Sea to help archaeologists excavate 12th-century shipwrecks.
