Is there any interactive software useful for learning the basics of the fourth spatial dimension?

The fourth spatial dimension has interested me for a long time and I’ve long wanted to understand it on a deeper level. Are there any games/simulations and such (preferably freeware) that could help increase my understanding of it? Some examples of software close to what I’m looking for are the upcoming puzzle platformer miegakure and magic cube 4d, but the former isn’t out and the latter isn’t beginner-friendly.
