Inserting a tag cloud widget into a page only shows a limited number of tags

I am using the tag cloud as a primary method of navigation in a wiki that aggregates news topics sorted by topic. I'd like to insert a widget on the home page that shows all the tags on the site, not just the ones that show up on the side bar (seems to stop at the first 20 or so tags).

Is there a separate widget that shows all the tags, or can one be created? I would love to insert the same tag cloud that I can see when I click the "More" link - a whole page full of tags - on the home page.
