Can I add dynamic content in boxes?

Boxes look nice, but I don't get how to use them. I'd like to have a box which shows an excerpt from the most recent post in a category? Is that possible or should I use something else?

You could try using a plugin/shortcode to do this: http://wordpress.org/extend/plugins/advanced-most-recent-posts-mod/faq/
