Up today is my 365DOA podcast, , Your Head is Jupiter.   It's a new variant on a standard bit I use in classrooms, only it's much cooler because IT USES A COMPUTER!  (woo!)

In it, you get to make a solar system at your desk, using your monitor as a sun.  You also get to lick your monitor, if you like.  Visit the link and either read the transcript or (gasp) actually listen to the podcast.
