Production environment: error page for fatal errors

[eluser]Unknown[/eluser]
Hi guys,

Do any of you know if there is a possibility to show a nice error page when a fatal error occurs? When you set the environment variable in index.php to 'production' the page just stays white, and I think it is convenient to show a page with some description.

Of course I could modify the default CodeIgniter code, but I would like to avoid that, so I am hoping one of you could help me out with some idea's.
