Displaying random posts on my main page

You need to create custom query loop with posts, and change order to random.

Figured that, not sure how to get to it tho :<

<?php $index_query = new WP_Query('post_type=post&showposts=10&orderby=rand'); ?>
<?php while ($index_query->have_posts()) : $index_query->the_post(); ?>
code here...
<?php endwhile; ?>

You need the paginator?
