Astazi am sa va prezint un script java (in combinatie cu css) care face ca dupa cursorul dumneavoastra sa se tina un anumit text ales de voi.

Cod
<style type="text/css">  
/* Circle Text Styles */  
#outerCircleText {  
/* Optional - DO NOT SET FONT-SIZE HERE, SET IT IN THE script */  
font-style: italic;  
font-weight: bold;  
font-family: 'comic sans ms', verdana, arial;  
color: black;  
/* End Optional */  

/* Start Required - Do Not Edit */  
position: absolute;top: 0;left: 0;z-index: 3000;cursor: default;}  
#outerCircleText div {position: relative;}  
#outerCircleText div div {position: absolute;top: 0;left: 0;text-align: center;}  
/* End Required */  
/* End Circle Text Styles */  
</style>  
<script type="text/javascript">  

;(function(){  

// Your message here (QUOTED STRING)  
var msg = "Flood of games";  

/* THE REST OF THE EDITABLE VALUES BELOW ARE ALL UNQUOTED NUMBERS */  

// Set font's style size for calculating dimensions  
// Set to number of desired pixels font size (decimal and negative numbers not allowed)  
var size = 12;  

// Set both to 1 for plain circle, set one of them to 2 for oval  
// Other numbers & decimals can have interesting effects, keep these low (0 to 3)  
var circleY = 0.75; var circleX = 3;  

// The larger this divisor, the smaller the spaces between letters  
// (decimals allowed, not negative numbers)  
var letter_spacing = 5;  

// The larger this multiplier, the bigger the circle/oval  
// (decimals allowed, not negative numbers, some rounding is applied)  
var diameter = 10;  

// Rotation speed, set it negative if you want it to spin clockwise (decimals allowed)  
var rotation = 0.4;
