Has anyone had any experience with Flint particle system? I’m basically trying to get it to output each particle in a certain point (x,y coord) and then getting it to move a certain way.

Another possible way is to use lineTo to draw a line, take a bitmap of that and then draw particles based on that…but that might be really slow.

Anyone have any suggestions?

I suppose I should explain more clearly – Im attempting to use Flint to create a colorful spectrum analyzer (for a given mp3 file). I have experience creating one using lineTo or drawCircle to create my own “particles” but I figured it would be neat to use the power of Flint to create some cool affects. Im hoping I can do this without too much cpu/ram usage.
