The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
This is a video of a plane moving through clouds. I for one find it extremely calming. Could you imagine being a bird? Must be how pilots feel. Flight is cool. Thank goodness the Write brothers were crazy enough to jump off the side of mountains with wings tapped to their backs. Anywho, this is the third video that was uploaded as a placeholder.
