代码如下:

<script><script>
<!-- Begin
if (document.all) {

yourLogo = "博易天下欢迎你的光临";  //Not less than 2 letters!
logoFont = "Arial";
logoColor = "ff0000";
//Nothing needs altering below!
yourLogo = yourLogo.split('');
L = yourLogo.length;
TrigSplit = 360 / L;
Sz = new Array()
logoWidth = 100;
logoHeight = -30;
ypos = 0;
xpos = 0;
step = 0.09;
currStep = 0;
document.write('<div id="outer" style="position:absolute;top:0px;left:0px"><div style="position:relative">');
for (i = 0; i < L; i++) {
document.write('<div id="ie" style="position:absolute;top:0px;left:0px;'
+'width:10px;height:10px;font-family:'+logoFont+';font-size:12px;'
+'color:'+logoColor+';text-align:center">'+yourLogo[i]+'</div>');
}
document.write('</div></div>');
function Mouse() {
ypos = event.y;
xpos = event.x - 5;
}
document.onmousemove=Mouse;
function animateLogo() {
outer.style.pixelTop = document.body.scrollTop;
for (i = 0; i < L; i++) {
ie[i].style.top = ypos + logoHeight * Math.sin(currStep + i * TrigSplit * Math.PI / 180);
ie[i].style.left = xpos + logoWidth * Math.cos(currStep + i * TrigSplit * Math.PI / 180);
Sz[i] = ie[i].style.pixelTop - ypos;
if (Sz[i] < 5) Sz[i] = 5;
ie[i].style.fontSize = Sz[i] / 1.7;
}
currStep -= step;
setTimeout('animateLogo()', 20);
}
window.onload = animateLogo;
}
//  End -->
</script>

代码说明 ： 直接添加到控制面板的自定义的代码里，类似css代码的添加方式。
