I need to animate the multiplying of bacteria.

Starting with 1 bactery, this one splits itself in 2 bacteria, these 2 in 4, these 4 in 8, these 8 in 16, etc. This is called exponential growth.

These bacteria also needs a sort of self collision so they can push other ones away. I think that an emitter solution is not possible because particles don't have self collision in Blender (am I right?)

With molecular script this could be solved (self collision) but then you only can work with spheres, not other objects (am I right?)

Maybe it's possible with animation-nodes but to complex for me.

Please take a look at the youtube link with real microscope footage! This will explain what I want.
