WOOH! Trippy man!! It's a Rainbow! This looks really good on Black backgrounds or with dark pictures! Just put this where ever you want some rainbow text!


Insert into <HEAD>


Insert into <BODY>
<script language="JavaScript"> <!-- Hide the script from old browsers -- function MakeArray(n){ this.length=n; for(var i=1; i<=n; i++) this[i]=i-1; return this } hex=new MakeArray(16); hex[11]="A"; hex[12]="B"; hex[13]="C"; hex[14]="D"; hex[15]="E"; hex[16]="F"; function ToHex(x){ var high=x/16; var s=high+""; s=s.substring(0,2); high=parseInt(s,10); var left=hex[high+1]; var low=x-high16; s=low+""; s=s.substring(0,2); low=parseInt(s,10); var right=hex[low+1]; var string=left+""+right; return string; } function rainbow(text){ text=text.substring(3,text.length-4); color_d1=255; mul=color_d1/text.length; for(i=0;i < text.length;i++){ color_d1=255Math.sin(i/(text.length/3)); "255Math.sin(i/(text.length/3))" color_h1=ToHex(color_d1); color_d2=muli; color_h2=ToHex(color_d2); document.write("<FONT COLOR='#FF"+color_h1+color_h2+"'>"+text.substring(i,i+1)+'</FONT>'); } } // --End Hiding Here --> </script> <SCRIPT> <!-- {rainbow("--> YOUR MESSAGE GOES HERE. THE LONG THE BETTER!<!--");} //--> </SCRIPT>

Other Options
Just put this where ever you want some rainbow text! CAUTION: If you use <font color = ""> make sure you close the tag with </font> If you don't you'll see this wierd effect an your program might crash. (At least it happens on my computer - Ne tscape 3.0 and Win 3.11)
