omvendt snevejr i java

Hej allesammen

Nedenfor er der et java script jeg har fundet.

Jeg kunne godt tænke mig at få snefnugget til at komme fra bunden af skærmen og op ad.

Kan det lade sig gøre?? og er der i så fald en der kan hjælpe mig med at få det til at lykkedes??

Her er script'et:

<script LANGUAGE="JavaScript1.2">
