Multi thoughts
I like to think that with four ears, each pair would have a different tuning to extend the audible range. Maybe a larger pair of ears that can hear 10~10000 Hz sounds, and a slightly smaller pair in front that can hear 40~40000 Hz sounds.
Likewise, multiple specialized sets of eyes can be neat as well. A pair of eyes that sees between 800~450nm in conjunction with a pair that can see between 650~300nm, for instance.
However little sense that makes biologically.

@Motodrachen well, while I'm thinking about fantasies I think I'll just fantasize about being able to process things like that too -w-

@Motodrachen Hmm. Do people _not_ generally see things like that? Watching things wick into paper is rather satisfying.
