Heheh, thanks guys

. Yes, this is indeed all TG, except for the ring of clouds around the tornado - that's just a doughnut-shaped image map that I whipped up (I suppose I could have done it with functions, but image maps seemed more practical this time

). Both the tornado and the dust cloud around it are masked by functions nodes. I definitely agree with darthvader that the ground is too noisy, and I'll experiment with other POVs as well. Stay tuned!
