OR you can simply project the fourth dimension into 2D, much like how we project 3D pictures onto 2D screens. Here's an example <a href="http://jakebian.github.io/hypercanvas.js/" rel="nofollow">http://jakebian.github.io/hypercanvas.js/</a>
I've thought a lot about visualising higher dimensions in 3D. Colour is a fantastic way to start, and it infact is adding 3 more dimensions (hue/saturation/lightness). If you could add other senses, e.g., touch, taste, pain, etc., you can sense even more dimensions.<p>However, one thing does strike you that no matter how many senses you incorporate, you will always navigate a particular 3D projection.<p>EDIT: Cached page: <a href="http://webcache.googleusercontent.com/search?q=cache:http://www.rdrop.com/~half/Creations/Puzzles/visualizing.4D/" rel="nofollow">http://webcache.googleusercontent.com/search?q=cache:http://...</a>
