Animation Engine: speed tips

[David Bovill]

Here is a short video of a really nice ball animation of the Earth’s Carbon Cycle - which is the sort of thing I’d like to make a series of animations / interactive simulations about. There a re a few more than 30-40 moving balls here - but they are more or less dots….

I wonder how many particles can be animated like this in Livecode...
