Browsershots – http://browsershots.org/
This complimentary service lets you test your Web design in 55 different combinations of Web browsers and operating systems. It’s a handy tool to show a client how different systems can mangle sites using nonstandard code.

Type in a Web address, select which browser/OS combinations to test, and click the button. Browsershots uses distributed computing to test your page across a network of users, who send back screenshots showing the results.
