脚本说明:
第一步:把如下代码加入<head>区域中:
<SCRIPT language=javascript>
<!--
pX=400;pY=200
obs = new Array(13)
function ob () {
for (i=0; i<13; i++) {
 if (document.all) obs[i]=new Array (eval(ob+i).style,-100,-100)
 else obs[i] = new Array (eval(document.ob+i),-100,-100)
 }
}
function cl(a,b,c){
 if (document.all) {
 if (a!=0) b+=-1
 eval(c+a+.style.pixelTop=+(pY+(c)))
 eval(c+a+.style.pixelLeft=+(pX+(b)))
 }
else{
 if (a!=0) b+=10
 eval(document.c+a+.top=+(pY+(c)))
 eval(document.c+a+.left=+(pX+(b)))
}
if (document.all) c0.style.pixelLeft=26
}

function runClock() {
 for (i=0; i<13; i++) {
 obs[i][0].left=obs[i][1]+pX
 obs[i][0].top=obs[i][2]+pY
 }
}

var lastsec
function timer() {
 time = new Date ()
 sec = time.getSeconds()
 if (sec!=lastsec) {

 lastsec = sec
 sec=Math.PI*sec/30
 min=Math.PI*time.getMinutes()/30
 hr =Math.PI*((time.getHours()*60)+time.getMinutes())/360
 for (i=1;i<6;i++) {
  obs[i][1] = Math.sin(sec) * (44 - (i-1)*11)-16;
  if (document.layers)obs[i][1]+=10;
  obs[i][2] = -Math.cos(sec) * (44 - (i-1)*11)-27;
 }
 for (i=6;i<10;i++) {
  obs[i][1] = Math.sin(min) * (40 - (i-6)*10)-16;
  if (document.layers)obs[i][1]+=10;
  obs[i][2] = -Math.cos(min) * (40 - (i-6)*10)-27;

  if (document.layers)obs[i][1]+=10;

 }
 }

}
function setNum(){

cl (0,-67,-65);
cl (1,10,-51);
cl (2,28,-33);
cl (3,35,-8);
cl (4,28,17);
cl (5,10,35);
cl (6,-15,42);
cl (7,-40,35);

cl (9,-65,-8);
cl (10,-58,-33);
cl (11,-40,-51);
cl (12,-16,-56);

</SCRIPT>


第二步:把<body>中加入如下代码:
<div id=c0 style=position:absolute;right:6;top:6; z-index:2;>
  </div>
     <div id=c1 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>1</b></div>
     <div id=c2 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>2</b></div>
     <div id=c3 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>3</b></div>
     <div id=c4 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>4</b></div>
     <div id=c5 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>5</b></div>
     <div id=c6 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>6</b></div>
     <div id=c7 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>7</b></div>
     <div id=c8 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>8</b></div>
     <div id=c9 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>9</b></div>
     <div id=c10 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>10</b></div>
     <div id=c11 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>11</b></div>
     <div id=c12 style=position:absolute;left:20;top:-20; z-index:5;font-size:11px;><b>12</b></div>
     <div id=ob0 style=position:absolute;left:-20;top:-20;z-index:1>  </div>
     <div id=ob1 style=position:absolute;left:-20;top:-20;z-index:8> <font size=+3 color=#0000FF><b>.</b></font></div>
     <div id=ob2 style=position:absolute;left:-20;top:-20;z-index:8> <font size=+3 color=#0000FF><b>.</b></font></div>
     <div id=ob3 style=position:absolute;left:-20;top:-20;z-index:8> <font size=+3 color=#0000FF><b>.</b></font></div>
     <div id=ob4 style=position:absolute;left:-20;top:-20;z-index:8> <font size=+3 color=#0000FF><b>.</b></font></div>
     <div id=ob5 style=position:absolute;left:-20;top:-20;z-index:8> <font size=+3 color=#0000FF><b>.</b></font></div>
     <div id=ob6 style=position:absolute;left:-20;top:-20;z-index:7> <font size=+3 color=#00FFFF><b>.</b></font></div>
     <div id=ob7 style=position:absolute;left:-20;top:-20;z-index:7> <font size=+3 color=#00FFFF><b>.</b></font></div>
     <div id=ob8 style=position:absolute;left:-20;top:-20;z-index:7> <font size=+3 color=#00FFFF><b>.</b></font></div>
     <div id=ob9 style=position:absolute;left:-20;top:-20;z-index:7> <font size=+3 color=#00FFFF><b>.</b></font></div>
     <div id=ob10 style=position:absolute;left:-20;top:-20;z-index:6> <font size=+3 color=#F30000><b>.</b></font></div>
     <div id=ob11 style=position:absolute;left:-20;top:-20;z-index:6> <font size=+3 color=#F30000><b>.</b></font></div>
     <div id=ob12 style=position:absolute;left:-20;top:-20;z-index:6> <font size=+3 color=#F30000><b>.</b></font></div>


第三步:把<body>中内容改为:
<body bgcolor=#fef4d9 onLoad=ob(),setNum(),setInterval(timer(),100);setInterval(runClock(),100)>
