if you know how to do animations for like flash or stuff you could easily learn over a day.
if you want to try all you need to do is to download 3ds max trial version/free, install it and then download the b3d pipeline at: http://www.onigirl.com/pipeline/
and the max6 patch at the same page. Install those and then download the jibberish custom pack at skigamemakers homepage.
Then open the file called Skier sept 24(1) text with 3ds max.
And there you have it, its a movie like thing, which is all the grabs. Press SET KEY soo you get a red frame. Just adjust at the end of each part of the movie where you see the grab ends and press the KEY to mark where it should be. That way it wont change its possiistion..
The press file and export. the change it to a BLitz3d (.B3d) file, name it Cross_in6 and push SAVE. The youll get up a checkbox or what to call it, i suck at english, and you have to make it look like this
not that hard eh?
