How to create some special effects for buttons?

I have 3 questions, sorry for asking too much when haven't contributed enough, I am kinda new so ... Anyway, those ideas might interest you:


I came over a site, cant remember now , but as you mouse over the button, the content glows from blur to clear. I would love to know how you would do that, involve java scripts I guess, dunno

And is that possible to make it a little more complicated like: buttons change color as moused over, or a sound effect appear when moused over ....


The last things I'd like to be told is how tp code to change some fixed texts, buttons into graphics boxes and graphics buttons. Like I want to change the "last thread" "next thread" or "Edit Quote report" "Post"" Join ""Status"" in my postbit box, the "submit reply ""Reset form" downthere, everything, into graphics boxes and buttons. You got the idea right?

Every little help will be highly appreciated

Thanks all very much
