I've searched for this but couldn't find an answer. I think it's probably simple, just not simple enough for me.
I've inserted a tag cloud on my front page using something like this:
<?php wp_tag_cloud( number=10&order=RAND ); ?>
So this generates a cloud of 10 randomly selected tags. So far, so good.
I'd like to add a button on the page so that users can reload the cloud (without reloading the page, ideally) so that they are presented with a new set of tags. Can anyone point me to a bit of code to accomplish this?
