Fodder for Other Planes of Existence

If you like to use other planes (or planets!) in your tabletop roleplaying setting but aren't always sure how to portray some of the harsher environments, check out this National Geographic video on their YouTube channel called "Naked Science: Storm Worlds."  Looks also get ideas about how to create symbiotic environments on the planet of your setting based off explanations of how real world environments and super-weather systems interact.  It's a 48 minute show with a few commercial breaks, though you know you can skip along through it if you just want to sample what they are exploring.  Enjoy!
