[Bf-python] Point clouds

[Ian Johnson]

Do the cubes have to be identical? What if one wanted to make different
cubes different colors? Are you moving the vertices around to create an
animation?

If i have 20k points which I want to move over time and have their colors
change, would particles be the way to go?

This is a very interesting discussion, thanks!
