I'm just curious as to what variable causes this. Right now we've got three different such groups with the sparkle feature: Waifu, Nyandere, and Nephilim. When you go to create a group though, there isn't any sort of option to implement sparkles. Is it just based on your color hex code? And if so, how do you know in advance what codes will enable it? It looks like all these groups were created by forum moderators, so is it exclusive only to mods when making a group?
If this is something that anyone can do, I feel like it should be common knowledge via a forum guide. (that is, if it's not explained within its own menu)
And this just opens up even more questions... Are there OTHER hidden visual effects we haven't seen used by anyone yet?
