kestral_kitsune, the 3D ones are made with some computer animator that is I hear VERY hard to use and the ones I put at the top of this thread were the best-implemented ones I've seen so far...but being modeled by computer is is tough to keep them from being sterile...generally they are labeled with "SFM" so if you don't like those, just skip "SFM"
Ponyfan, I've edited to put all the contributions so far in the original posting for everypony's convenience, I put your G1 one in big font to make it harder to miss...but, the format is a total mess maybe I'll try to clean it up a bit later if I have time.
Everypony (and by this I mean all gens of course I just love the any-every-pony Thing from G4 don't mind me!):
Thanks So Much for the contributions and feel free to keep em coming!!
