4D and
5D Rubik's cubes (here are previous
Slashdot posts on
the 4-D one and
the 5-D one)
have now developed a free
working 4-dimensional software analogue of the
Megaminx puzzle. Composed of
120 dodecahedral cells, the
underlying structure is arguably the most beautiful of 4D geometrical shapes,
with amazing symmetries and no analogue in dimensions higher than 4.
Though some have already begun working on solutions for this 'Hyperminx,' it has
yet to be solved by anyone. Also, when it comes to
number of positions, it dwarfs the previous puzzles by many thousands of
orders of magnitude!"

If you'd watched the linked clip, or even considered that perhaps there are people who can do it with their feet, you'd see that this video is not faked. The cubing community uses commercially available puzzle pads, both for hands and feet: remove hands from pad and timer starts, return hands and timer stops.
This guy uses the foot mat (complete with little foot graphics on the contacts instead of hand graphics), and the timer counts forward as the puzzle progresses from unsolved to solved, then he jumps down and resets the timer without stumbling around awkwardly. Have a look because it's pretty impressive to see someone manipulate anything that well using just feet and toes.
