Generating a bacteria colony

Hi, please take a look at this real footage of multiplying bacteria https://www.youtube.com/watch?v=gEwzDydciWc

How could I do this in Blender?

Thanks!

Think of the entire colony video as a single 3D structure which you are viewing as a 2D plane passing through it. Like a CAT scan. Build the colony tree like structure in 3D then use a boolean modifier to pass a thin cube slice through it.
