I threw this together in Animate to get an idea of how a particular scene in my animation could look. I am going to go for a big choreographed dance number that would begin inside a single cell and then zoom out to reveal lots of cells. At this point in the animation a voice over would explain that mitosis takes place all over our bodies all of the time. This is too fast, but I am pleased with the outcome otherwise and I am going to do some searching for ideas about other possible patterns for my animation.
Here is a slower version.
