How would i go about creating this flash effect?

i want to build a site with wordpress, so i can use wordpress for the content management, but i need a very flash oriented background for the site. i need to do something very similar to the flying cherry effect that you see on <a href=“”>this site</a>.

i’m very much a flash newbie so if the answer is very technical, please keep that in mind. basically, i don’t have the slightest clue how to incorporate the two so i’m looking for some guidance.

please advise. thanks in advance.
