Website lets you view old websites with old browsers

Oldweb.today lets you view archived snapshots of the web (from the Wayback Machine) in old browsers. It has all of the important ones, from NCSA Mosaic through the Netscapes and Mac IE to the present day. [via JWZ.]

You can of course use it to view present-day sites in old browsers, too. Netscape 3 chokes pretty badly on jQuery!
