4D Toys

4D Toys lets you explore interactive objects in a fourth spatial dimension. You can poke, throw and roll the toys, watch them disappear into a dimension you cannot see, and experiment with how objects bounce, slide and roll in more than three dimensions. The game supports VR and regular screens.

Explore four dimensions

A 4D spatial dimension works like the three familiar dimensions; when time is counted as well, the toys are 5D. The game uses a 4D-and-time physics system based on new mathematics developed for the project. Its 2D/3D “Flatland” explanation teaches the idea of a fourth spatial dimension by analogy.

There are over 100 interactive scenes. You can roll 4D marbles across 4D terrain, play with a non-intersecting 4D Klein Bottle, fit a hypercube into a hyperhole and unbind rings using the fourth dimension. You can also set up levers that throw hypercubes into the fourth dimension, squeeze objects into it, play in a 4D ball pit, and watch tesseracts slide down slopes.

Play with 4D objects

You can use the Anti-Gravity feature to make 4D objects levitate, stack and smash 4D hypercubes, or set up paths for 4D dominoes. The shapes can also serve as symmetric dice with 5, 8, 16, 24, 120 or 600 sides. Meshes can be exported for 3D printing.
