text dynamics, help me sort it out…Please!

Well, I found that script on a site, it’s made to control several types of animations…

I changed some parameters to have it do what I want but then it was slow (because the browser was doing things it shouldn’t) and when I tried to ‘clean out’ the script from unneccesary info, it stopped working properly…

I’m still a newbie at JS… That’s probably why I couldn’t make it to work properly… ?

Take a look here: a [URL=http://www.scriptsplus.com/scripts/image/dynamique.php#]Sample[/URL] (when you are on that page click on “Voir l’exemple” to see the sample)

The thing I want to do is to have the whole alphabet fall down, letter by letter, from the top of the page on page load (it’s what ‘Exemple3’ does on the sample…) but when I change the number of ‘steps’ to 24, it slows down so much it doesn’t look good anymore!!! ?

Can you help me with this??? Thanx

Here’s the code:
