Protei is an articulated, opensource autonomous sailing robot, initially designed to cleanup oilspills by puling a long oil absorbent boom.
Mind boggling innovations:
Crazy, brilliant stuff.
Truth be told, It doesn’t look like much, really just some dude’s basement, and the music leaves much to be desired, but hot damn, can that robot do the highbar!
And a double back handspring!
Here’s a quintuple backflip:

The problem of beer: That it is within a ‘bottle’, i.e. a boundaryless compact 2-manifold homeomorphic to the sphere. Since beer bottles are not (usually) pathological or “wild” spheres, but smooth manifolds, they separate 3-space into two non-communicating regions: inside, containing beer, and outside, containing you. This state must not remain.
A proposed solution: Clearly the elegant course is to introduce a non-orientable manifold, which has one side and does not divide 3-space. When juxtaposed with the beer-bounding manifold described above, it acts to disrupt the continuity thereof, canceling the outdated paradigm of distinction between interior and exterior. This enables the desired interaction between beer and self.Implementation The Klein Bottle Opener shown above is an example. It is palm-sized, durably constructed in stainless steel, effective, and blissfully ergonomic. Q E D You need one.
Because they believe that to be “seen” they have to see the other person.
… it would seem that children apply the principle of joint attention to the self and assume that for somebody to be perceived, experience must be shared and mutually known to be shared, as it is when two pairs of eyes meet
Fascinating.
Why do children hide by covering their eyes? from the British Psychological Society.
Octopus are truly the closest thing to alien intelligences that exists on this planet. If we ever do meet creatures from another world, the experience will be less like trying to communicate with someone from another country or even like trying to communicate with an elephant or a dolphin, and much more like trying to get inside the squishy, gelatinous head of an octopus.
from Scientist from an excellent discussion of Octopi.
