4D Analogue of Megaminx Puzzle
roice writes "The crazy hypercubists who created the
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!"
Allow me to shove your head under the putrescent waters of depression.
Three year old solves rubik's cube in less than 2 minutes.
6 year old solves rubik's cube in 40 seconds.
Guy solves rubik's cube in 20 seconds with one hand.
Guy solves rubik's cube in 50 seconds -- with his feet
\I can't solve it either

For a true 4-dimensional Rubiks Cube, one that incorporates Time. Of course solving it will be incredibly disappointing, since after you do solve one, it turns out that it was solved all along.
Here you go, it's already been invented: http://gizmodo.com/gadgets/rubik.s-cube/the-idiots-cube-256889.php

Ever played the latest Prince of Persia (Sands of Time) series? They were 3D games where you had to use another dimension (time travel) to navigate puzzles because things were [un]available in different times. Heck, go back to Zelda series for a 2D game where travel to a dream-world allows more freedom of movement.
actually, what we see on the screen is a two-dimensional representation of the three dimensional representation of the four-dimensional object :-/
Perhaps you're thinking of Michel Gondrey's moderately infamous trick.
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.
