Falling cherry blossoms or snow transitions

I'm in the proess of doing a DVD in which I have a cherry blossom clip as an introuduction. I want to use, preferrably cherry blossom petals transitions. However, if that is a tall order then I could settle with snow. I dont may paying for the transition set if there is one available or somebody can suggest something that might do the trick.

Thanking you in adance,
