Clues:
This tool has been tested on Netscape Navigator 7.2, Internet Explorer 6.0, and Firefox 1.5. It works as designed on all three, but on IE it is not very pretty. It requires JavaScript, so if you are having problems with it, please make sure that JS is enabled in your browser. The source code, and other neat things, are available at www.phrebh.com.
