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. However, one thing does strike you that no matter how many senses you incorporate, you will always navigate a particular 3D projection.
