Add Useragent to the body class?

something like this maybe:

function my_class_names($classes) {
    $useragent = $_SERVER['HTTP_USER_AGENT'];
    if(strchr($useragent,'Safari')) $classes[] = 'Safari';
    // etc..
    return $classes;
}
add_filter('body_class','my_class_names');

Edit – as per Chip’s suggestion, here’s the function using the WordPress useragents checks:

function my_class_names($classes) {
    global $is_lynx, $is_gecko, $is_IE, $is_opera, $is_NS4, $is_safari, $is_chrome, $is_iphone;
    if($is_lynx) $classes[] = 'lynx';
    elseif($is_gecko) $classes[] = 'gecko';
    elseif($is_winIE) $classes[] = 'winIE';
    elseif($is_macIE) $classes[] = 'macIE';
    elseif($is_opera) $classes[] = 'opera';
    elseif($is_NS4) $classes[] = 'NS4';
    elseif($is_safari) $classes[] = 'safari';
    elseif($is_chrome) $classes[] = 'chrome';
    elseif($is_iphone) $classes[] = 'iphone';
    else $classes[] = 'other';
    return $classes;
}
add_filter('body_class','my_class_names');
