Leave it to Brad over at Liliputing.com.   He's known for getting some of the latest tech news around and for making some fantastic 'how-to' videos, especially when it comes to installing custom ROMs and that sorta thing.   Well Brad recently took ownership of a new Windows 8 tablet sent to him by the folks over at  Kupta and he realized he couldn't find a good source for all the Windows 8 touch gestures to be used with the Metro UI.  So of course Brad took the lead and has put together this fantastic video above that walks us through all the touch gestures available for Windows 8.  There are a total of 9 and Brad walks you through them all in order:

1. Swipe from the right (Charms menu)
2. Swipe from the left (Switch apps)
3. Swipe slowly from the left (Snap apps)
4. Swipe from left-and-back (Show running apps)
5. Pull down from the top (Close app)
6. Swipe down (Bring up additional menus)
7. Swipe down on an item (Select)
8. Pinch (Zoom)
9. Swipe left/right in Internet Explorer (Move back, forward)
