Problems with showing random and limited bookmarks

All new to this forum, so please forgive me if it is the wrong forum.

I am trying to create a plugin/widget that shows 5 randoms bookmarks from the links database.

this is what i got:

function widget_content(){
  global $wpdb;
  $results = $wpdb->get_results("SELECT * FROM $wpdb->links WHERE link_visible ='Y'");
  $results = shuffle($results);
  $results = array($results);
  $results = array_slice($results, 0, 5);

  echo "<ul>";

    foreach ($results as $input) {
      $name = $input->link_name;
      $desc = $input->link_description;
      $url = $input->link_url;
        echo "<li>";
        echo "<a href=\"$url\">$name</a>";
        echo "</li>";
    }

  echo "</ul>";
}

Any idea what i am doing wrong?
