[chuck-users] Analyse voice and choose animal

[Will Grant]

What about maybe bypassing some of the computation by including a  
human game in the process?  E.g., make a spectral analysis of a  
participant's voice, then make a game of matching up visual patterns  
in that analysis with visual patterns in animal analyses.  After  
selecting patterns that seem to match, the action could return to  
something computational, like vocoding.  Maybe morphing from their  
spectrum to the animal's spectrum...

This may be irrelevant to your intentions!  but Nuno's idea caught my  
imagination, and this is what came to mind.
