SevenUp is a nice and nifty project through which you can help the world by trying to get rid of IE6.

It is a small 1k Javascript that displays a gentle CSS lightbox to encourage people who visit your site using IE6 or lower that they should consider upgrading their outdated browser. The script also includes an upgrade link to the newer version and also an option to dismiss the reminder and never bother again. The users of other browsers will be completely unaffected and will have no clue about the script present.

Hats Off to @staringpolite who has created this nice little javascript. So do your part and save your less techie friends from the evils of IE6.
