Beautiful widgets has unlock animations but they are too slow loading and arent worth it. Weather & toggle has them too but so far all i have seen is clouds...but they load just as fast as Sense. That could be a good widget but needs a little bit more work.
For the functions of launcherpro i gladly give up my sense animations. My hunch is that since pauncherpro is being re-written it can have the possibility of supporting animations just like sense. I think unlock animation may run better from the launcher then on top of it...but i'm not sure how all that works.
