"I am not sure that I've ever seen a more compelling 'show-don't-tell' educational tool than 4D Toys." –Ars Technica

What if you received a box filled with mysterious toys from a fourth spatial dimension?

• Playfully explore and marvel at beautiful shapes powered by a groundbreaking 4D+time physics system.
• Poke, throw, roll and watch as they disappear into a dimension you can't see.
• Get an intuitive feel for how four-dimensional objects behave:
• Become a child of the fourth dimension.

In this case the 4D is not time but a 4th dimension of space that works just like the first three dimensions we are familiar with. If you count time these toys are 5D. It turns out that the rules of how objects bounce, slide and roll around can be generalized to higher dimensions, and this unique toy lets you experience what that would look like.

Features:
• Over 130 beautiful interactive scenes to play with, with more to be added in updates.

• Groundbreaking 4D+Time Physics Engine that uses new mathematics created for this project.

• Multi-touch & Accelerometer support for rich interactivity.

• 2D/3D "Flatland" Interactive 10 Page Book/Explanation that teaches by analogy about a fourth spatial dimension.


Some things to do:

• Manage to fit the hypercube into the hyperhole!
• Use the 4D shapes as fancy, perfectly symmetric, fair dice that have 5, 8, 16, 24, or even 120 and 600 sides!
• Unbind Rings using the fourth dimension!
• Make a stack of 4D hypercubes and smash it!
• Set up an interesting path for a few 4D dominoes!
• Make levers that throw hypercubes into the fourth dimension!
• Use multitouch to "squeeze" out objects into the fourth dimension!
• Play in a 4D ball pit!
• See Tesseracts (i.e. 4D hypercubes) slide down slopes!
• etc...!

What’s New

Version 1.1

Added 11 new star-like shapes that would look great hanging from or on top of your 4D Christmas Tree.

The Regular Star Polychora (or "Schläfli-Hess 4-polytopes"):
* Icosahedral 120-cell
* Small stellated 120-cell
* Great 120-cell
* Grand 120-cell
* Great stellated 120-cell
* Grand stellated 120-cell
* Great grand 120-cell
* Great icosahedral 120-cell
* Grand 600-cell
* And my *personal favorite*, the Great grand stellated 120-cell

Plus a Compount 5-Cell for good measure.

The Star Polychora are the 4D equivalent of the 2D Star Polygons. Star polygons can be made by extending the edges of polygons, until they meet outside of the polygon. For example the "Star of David" can be made by extending the edges of a Hexagon. This process of extending edges (or faces and cells in 3D or 4D) is called Stellation.

Warmest wishes for a Happy Holiday Season and a wonderful New Year! I felt the need to take a break from updating 4D Toys for a bit, but more updates will be coming next year!

No 5.5" screen suport?

Dear dev, your idea is very interesting but poorly implemented on iOS. Please learn how to use Autolayout and reconsider where you intercept the gestures because it's extremely frustrating.
2 stars for launching a product with a great idea but without proper testing and with big design flaws.

I will ask for a refund but if you'll manage to make it work as it's supposed to, I'll buy it again.
