IE7 in IE5/6

Only a year or so late, but I came across a great little bit of javascript, aptly titled 'IE7', written by Dean Edwards. It's a set of javascript code that can be included in a page to bring IE5/6's CSS support up to a par with modern browsers like Firefox. I haven't tried implementing it in a site yet, but the IE dev team gave it their support as an interim option some time ago and it looks pretty well done anyway.
