Following up on the basics from The Center of PerlMonk Mass, I've gotten a cron script that runs every 10 minutes that grabs the XML from the PM Statistics page, and another from the PM Other Users nodelet; combines that info, and generates a map of the current PM users on the globe; this time, I've also included the day/night map as well as a current (+/- 3hrs) cloud map for the earth. Now you can tell at a glance who is waaaay up past their bedtime... ;-)

You can view the maps here.

Update: I should have posted the code as well; it's not too hard to extrapolate from the previous one, but...
