I just came up with this and I have been called a sick little monkey because of it: Nyan MLP. Take any pony, put a Pop Tart cutie mark on her rump and have her galloping through the universe with a rainbow trail like a Tron light cycle. I will commission anyone who can do it and the animation can be based on the original one or brand new, preferably with the music but it is not necessary.

So who's up for it?
