IE6, 7 upgrade warning script?

I once came across a site that offered an attractive web toolbar that notified you that you were using IE6, 7, and possible older versions of Firefox and suggested a method of updating the browser. Does anyone know where I can find this script?

You could just do it with CSS, whereby you have toolbar in the HTML and hidden for all browsers but IE6 and 7.

Hi, I’m aware of that, but I am looking for this site and was hoping that someone knows the URL.

Was it this?

Yes, that’s the one. Thank you.
