Interesting growth.
Bumping for ideas.
I will throw out that I have heard through urban sw myths that's it's a response to lighting.

Looks like it’s “bouncing” which supposedly is caused by lighting or so it’s believed.

yeah like what's already been stated it definetly seems to be "bouncing" and not anything malevolent, very cool!
