Cool, thanks for your feedback. Information about pagination and the template tags is currently found in the FAQ (http://wordpress.org/plugins/wp-tiles/faq/). Is the information here too sparse, or would you expect it somewhere else? Appreciate your comments!
As for loading a random template – that’s a nice idea. Currently, the templates are the only options that are not filterable by plugins or theme code. I’ll put it on the road map to include as either an option, or to make this more doable with custom code.
For now, if you really want to, you could could change the template by outputting javascript that manipulates the wp-tiles-data after the plugin has outputted.. (but this is very hacky)
Personally, I have pagination does not work – all the time only shows the first 20 positions. Index.php code is:
<?php get_header(); ?>
<div class="tiled-posts-div">
<?php query_posts("cat=&paged=$paged"); if (have_posts()) : ?>
<?php if ( function_exists ( 'the_loop_wp_tiles' ) ) : the_loop_wp_tiles(); endif; ?>
<?php else : ?>
<?php endif; ?>
</div>
<?php get_footer(); ?>
