That splash screen reminds me of some of the default desktop pictures that come with Mac OS X, as well as some of the stock Windows Vista graphics too. I wonder how it was originally made; looks almost like ribbons!
I'm enjoying using Filter Forge to create http://torley.com/textures |

i would think you could do it with perlin, but exactly how, i'm not sure. an interesting problem, though.
If wishes were horses... there'd be a whole lot of horse crap to clean up!

To my eye that looks like a photo of real smoke, combined with photoshop's 'apply gradient'.
Something similar could be made in your 3d program of choice without too much difficulty. |

cashcash, I tried using Cinema4D to do this but couldn't get close enough.
uberzev, that's nice, but the density is too strong. It would be nice if you could explain how you did it. 
BTW, I have found a cool plugin for photoshop that makes neat fractal like curves: Check this out: http://www.philipp-spoeth.de/photoshop/sinedots2.php Using that plugin I was able to get that effect but not close enough though.

i dont know. i think uber's is pretty damn close.
but how about an FF rendition? i would think a stretched perlin with maybe a threshold and set alpha to catch one portion and then colorize...or something along those lines, would work. If wishes were horses... there'd be a whole lot of horse crap to clean up!

Amazing stuff uberzev!
I noticed that the fumes aren't streched well but broken into "blobs",specially when you reduce the stretch value.I'm trying to get the fumes you see from a candle after you blow it off. Right now it's a mumbo jumbo of fumes one over the other. If you look at the fume here http://www.vividgeeks.com/ it is a single continuos flow. While the spectrum looks nice, different colours of fumes or maybe a tint setting would be cool, and another setting I would include is the rotation of the spectrum. Appriciate your work uberzev! |

This was done in c4d without any fancy advanced rendering stuff. I think it comes pretty close.

cashcash, how did you do that, looks nice!
I used a plane and then put a cloth tag to stimuate the fumy effect but couldn't get the shading properly |

Make a plane, put a twist deform on it. For the material use fresnel in the color channel, additive transparency, then put some noise in the displacement channel. Light accordingly....
