yep.

i made a litle try with canvas (you can see it on the 00_pmpd exemple) : 
the problem was that position was integer and not float, numerical 
imprecision where to important.

I also tried with data structure, but then the problem was that i don't 
have time to finish. but it's still on my todo list...


pmpd as a good place between user action and computer reaction.
using data structure is a good solution that I want to try.
