Fun with Theme Switching

With this you can amuse yourself by browsing to /node/1?theme=marvin
UPDATE: CODE REWORKED THANKS TO CHX
<?php
/**
* Implementation of hook_menu (D5 code)
*/
function SOMEMODULE_menu($may_cache) {
if (!$may_cache) {
if ($theme = $_GET['theme']) {
$themes = list_themes();
if (isset($themes[$theme])) {
$GLOBALS['custom_theme'] = $theme;
}
}
}
}

I was thinking this could actually be useful- for example you could make an all xml theme and have Flash get data from path/to/page?theme=xml_theme

SECURITY HOLE!!!!!!!!!!!!!!!!!!!!!!!
Drupal is NOT prepared for any random crap to be in $custom_theme. You must validate against theme_list(). Also, if this is Drupal 5 then this is not the right place, you should use hook_menu !$may_cache . Please update your post.
You can find similar code in
You can find similar code in Switchtheme module ( http://drupal.org/project/switchtheme )
Should be ok
Chx: In init_theme it looks like the $custom_theme gets validated against list_themes before being set. Still I edited my code to your suggestions just to be safe. Thanks.
Wow!
This looks to be a powerful technique. Thanks for sharing it! I could see a potential use for this in the upcoming Embed Widgets module as well.
