## 4D Analogue of Megaminx Puzzle80

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.

\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.

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.
