This is one of the most popular scripts in Javascript history. It is also one of the hardest to find. This displays text in a way that it appears as a bubble scrolling across the screen, enlargening the text as it goes. I would HIGHLY recommend this script for people that want to scroll text on their page in a unique way. Color coding at bottom shows the regular changes that you need to make, such as speed and text. 
<script language="Javascript">

var text  = "this is the bubble banner"
var speed = 200

var x = 0

function bb() {

var a = text.substring(0,x)
var b = text.substring(x,x+1).toUpperCase()
var c = text.substring(x+1,text.length)

window.status = a + b + c

if (x == text.length) {
x = 0
}

else {
x++
}

setTimeout("bb()",speed)
}

bb();

</script>

This is the text in lower case that scrolls across the screen.
This sets the speed that the "bubble" moves over the text. It is expressed in 1/100 of a second, so 200 would be 2 seconds.
