A simple little script that creates a random walk for selected objects. The script can be downloaded from random walk.
I’ve made two quick demonstration animations:
The second was made by grouping nine spheres into a metablob. Eight of the spheres in the metablob were then selected and the script run to add an animation to them. If you’re attempting something similar don’t try to select all the objects in the metablob. This results in all the objects getting the same animation as the metablob object itself becomes animated.
