        I should have mentioned that the Tektronics System was tried out
in the drumset reality I posted (or tried to post) several months ago.  The
results were pretty good.  Hitting the drumheads was much easier with the extra
depth information.  

For those who don't know (or couldn't guess given the number of people who've
played with this idea) this reality involves a rendered
drumset (2 snares, 2 toms, bass, 2 cymbals, and a "cow" bell...it goes moo).  
Two drumsticks with Polhemi sensors attached two them are used to interact
with the system.  As the two drumsticks are moved, rendered versions of them
are displayed real time on the screen.  Predictive filtering is used to 
compensate for delay.  The drums make the appropriate sound when given an
impulse with the drumsticks.  Csound is used to generate (or in some cases
play back samples) sounds for the system.  The sounds have in the past been tied
to the size and shape of the object (though nothing complex). All this is runnin
