Try something nonconventional.  Making this picture, I wasn’t looking for this effect at all, but after turning off a few layers, this pretty much made itself, and I liked the look.  There might also be a video sometime soon (the original purpose of doing the image), but it’s something I’ve never seen done, and it probably won’t look that cool.  So this teaser is probably cooler than the actual thing.

Now that I’ve raised your level of excitement to the roof, I’m out.  ;)
