Hello, on the Exo Wiki I saw that they are using some sort of animated background on all Wiki pages which gives the effect of falling snow of sorts.. I want to know how do you do this? I guess such an effect will require Java but can I use it even if I'm not an admin?

Link to Exo Wiki so you know what effect I mean: Exo Wiki
