thanks frank, I will look into it. do you have any benchmark test data 
about the speed of pyode compared to pmpd or msd?
I basically need only 2d at the moment. with pmpd I think I can draw at 
least 100-150 objects, maybe more(?). but that depends on the framerate, 
and many other factors (like how many of the objects are linked to each
