Stupid question about forum quirkiness

[Christoffer Lernö]

If one looks at the forum icon explanations there are these moving icons for popular threads.

However, during my time here I've never ever seen a moving icon. Is that feature turned of, or does a thread need to accumulate insane amounts of postings to get that icon or what?

Just feels weird it's there but nothing happens.

okidoki. That explains things. Now maybe I can sleep better at night, not having to worry about that mystery anymore.
