Well, what's interesting about 4D is that's not just an extra dimension slapped on top, it's extra rotational degrees of freedom. You can't really get that with time (at least not until you get relativistic, and it still would be hyperbolic rotation, not euclidean).

Sure you do - waves only exist in 4D as they have a time vector (frequency).

		What I'm talking about is something like this: https://en.wikipedia.org/wiki/Rotations_in_4-dimensional_Euc... You can either sweep a cutting hyperplane through time or rotate a fixed projection or cut through time, but not both simultaneously.
