JAVA Script Q - Making a little image follow the cursor...

Factual Questions
1

I’ve gone to web pages before where there’s a little sparkle that follows around the cursor, like you are waving a wand…I’ve also seen ones where a little cat or something chases the cursor as you navigate through the web page…HOW do you do that? I would love to know…

Thanks

There’s a whole category devoted to mouse trail effects at Dynamic Drive (DHTML cut-and-paste scripts).
