Hi John,
The code is called an invisible frame redirect, and I put the html up on a page located at:
http://www.cyberwave.com/invisible.html
There's a problem with this trick, and that is some versions of Windows running some versions of Explorer will constantly refresh the page. This hurts the user experience, and can screw up your stats if you are using pop-ups. I'm pretty sure the GoDaddy.com "mask" has this problem as well.
Nonetheless, it can come in handy in certain circumstances.

Amazing pop-ups make more sales!
