You want people to randomly submit new animations for 1.25? There's been no announcement at all about 1.25, although someone wants to rebuild JJ2, but that's not 1.25. I'd reckon he/she'd need enough time implementing the animations that already exist, let alone implementing random new animations.

If you want to make new animations, you should first decide, probably along with whoever needs them, what kind of animations you need, what the requirements are, the limitations (size, colours, amount of frames). I don't think randomly asking for animations will work. You need to invest some effort in organising at the very least.

If you do NOT want to make new animations but just need old ones, you should first discuss which ones are most imporant and which ones you want.
