4D Toys, eine nette iPhone-App (hab sie noch nicht installiert, DL läuft grade), ein Spielplatz voller Bauklötze aus der vierten Dimension.
4D Toys doesn't take you through carefully-constructed successively harder challenges the way Miegakure does. It's just 4D shapes, as if you were a very young kid again and given a box of wooden toys. Since the toys are 4D, that's sort of true: you have no experience playing with 4D shapes.
Play is undirected and we don't expect a child to come up with verbal realizations of what they are doing. They can learn about making stacks, and gravity, and fitting shapes into holes, and that could form the foundation for future, verbal, learning. Alternatively, one can just look at how pretty it is, like the waves rolling down the ocean, or the intricate swirling patterns in a fire.
It's so exciting to me to see a pile of hypercubes or a rolling 120-cell. Most representations of a fourth dimension are so abstract (a spinning bundle of lines) and my work has been to get away from that. It's the first time anyone has seen these objects as physical objects that bounce and roll and can be grabbed!
Das Game kommt übrigens von demselben Herrn, der vor drei Jahren das sensationelle Miegakure vorstellte:
Miegakure is a puzzle-platforming game that lets you explore and interact with a 4D world. The fourth dimension in this game is not time, it works just like the first three: it is a mathematical generalization.
You see three dimensions at a time and at the press of a button one of the dimensions is exchanged with the fourth dimension, allowing for 4D movement.
Your ability to move in the fourth dimension in addition to the usual three allows you to perform miraculous feats like walk through walls, see inside closed buildings, steal objects from closed containers, make object float in mid-air, bind two separate rings without breaking them, etc...
These actual consequences of the mathematical formulation of 4D space have been imagined for more than a century (in the 1884 novella Flatland for example) but it is the first time anyone can actually perform them, thanks to the video game medium.
