I've seen that before, it seems to be a mapping strategy rather than  
a strategy to explore the possibilities before making the mapping.  I  
say that because you have to decide the relationship of the  
parameters to the 2D space in order to get any sound out.  So I would  
be back to where I am now, in a sense.  I guess the idea could be to  
set up a timbre space for quickly interchanging and exploring the  

Perhaps using some kind of neural network thing would be more  
appropriate to exploration.  I could see something that is set up for  
exploration, which feedback like "make it more different" vs. "make  
it more similar", or "wider timbral range" vs. "smaller timbral  
range".  Also, a random mapping button would be useful to give you  
something unexpected.
