安装： 拷贝以下代码贴在网页紧接<body>标记之下。

<style type="text/css"> #supertext { position:absolute; left:0; top:0; visibility:hide; visibility:hidden; } </style> <script language="JavaScript1.2"> //Configure the below three variables //1) Set message to display (HTML accepted) var thecontent='<h1><font color="#FFFF00">Is This Annoying You Yet</font></h1>' //2) Set delay after which message should be hidden, in miliseconds ('' makes it incessantly visible on the screen) var hidetimer=''; //3) Set speed of animation (1-50), where larger is faster var BallSpeed = 10; ///NO NEED TO EDIT BELOW THIS LINE/////////// var contentWidth; var contentHeight; var maxBallSpeed = 50; var xMax; var yMax; var xPos = 0; var yPos = 0; var xDir = 'right'; var yDir = 'down'; var superballRunning = true; var tempBallSpeed; var currentBallSrc; var newXDir; var newYDir; function initializeBall() { if (document.all) { xMax = document.body.clientWidth yMax = document.body.clientHeight document.all("supertext").style.visibility = "visible"; contentWidth=supertext.offsetWidth contentHeight=supertext.offsetHeight } else if (document.layers) { xMax = window.innerWidth; yMax = window.innerHeight; contentWidth=document.supertext.document.width contentHeight=document.supertext.document.height document.layers["supertext"].visibility = "show"; } setTimeout('moveBall()',400); if (hidetimer!='') setTimeout("hidetext()",hidetimer) } function moveBall() { if (superballRunning == true) { calculatePosition(); if (document.all) { document.all("supertext").style.left = xPos + document.body.scrollLeft; document.all("supertext").style.top = yPos + document.body.scrollTop; } else if (document.layers) { document.layers["supertext"].left = xPos + pageXOffset; document.layers["supertext"].top = yPos + pageYOffset; } animatetext=setTimeout('moveBall()',20); } } function calculatePosition() { if (xDir == "right") { if (xPos > (xMax - contentWidth - BallSpeed)) { xDir = "left"; } } else if (xDir == "left") { if (xPos < (0 + BallSpeed)) { xDir = "right"; } } if (yDir == "down") { if (yPos > (yMax - contentHeight - BallSpeed)) { yDir = "up"; } } else if (yDir == "up") { if (yPos < (0 + BallSpeed)) { yDir = "down"; } } if (xDir == "right") { xPos = xPos + BallSpeed; } else if (xDir == "left") { xPos = xPos - BallSpeed; } else { xPos = xPos; } if (yDir == "down") { yPos = yPos + BallSpeed; } else if (yDir == "up") { yPos = yPos - BallSpeed; } else { yPos = yPos; } } function hidetext(){ if (document.all) supertext.style.visibility="hidden" else if (document.layers) document.supertext.visibility="hide" clearTimeout(animatetext) } if (document.all||document.layers){ document.write('<span id="supertext"><nobr>'+thecontent+'</nobr></span>') window.onload = initializeBall; window.onresize = new Function("window.location.reload()"); } </script>

Find this line in the script to specify the text, font size, and font color.
var thecontent='<h1><font color="#FFFF00">Is This Annoying You Yet</font></h1>'

Find this line to set the animation speed.
var BallSpeed = 10;

就是如此简单！
