I've always liked those hurricane images, so I had a little idea in my head:
It would be nice if we could add a
vortex point anywhere we want. (This will of course only affect the clouds). A point which allows us to set the eye-size, biggest size, drag force, rotation and stuff like that. Maybe even something to make it start from the ground so we have a tornado.
I don't know..... maybe this is impossible, but I thinks it's a great idea
