Schneeflocken

Ideal zur Winterzeit,
mit diesen Javascript kann man diverse Dinge über den Bildschirm herrabrieseln lassen.

Im Klartext das Bild mit dem Namen snow.gif wird mehrfach über die Seite bewegt, was den eindruck erwecken könnte das es schneit.

Dabei kann man einstellen wie wie oft das Bild gleichzeitig gezeigt werden soll, und auch wie schnell der Schnee fallen soll...
