I love that video of Ben Burt showing how he made winds for WALL-E by dragging that boxing bag around on a lino floor - see at 7 minutes in this video http://www.youtube.com/watch?v=TSf8Er2gV_Q
So what interesting things have you done to create wind sounds? (No fart jokes thanks)
I'm working on a short film Goutte d'Or at the moment and just made some spooky winds using howling wolves pitched down 2 octaves and same for dragging a heavy wooden couch around on a wood floor....
