PHPThrowdown is a 24 hour coding marathon for PHP, which started yesterday. PhpNut and gwoo participate in this marathon in the category “inventory management” with an application called “Itemizr” (see some screenshots). You can follow their progress on http://cakephp.blogture.com/. Good luck to PhpNut and gwoo!
Update: The application is available at http://itemizr.cakephp.org.
