Smoke & Fog effect

[hetal]

hi,
i'm trying to create an effect of fog & smoke in the background.
At the moment, i'm using bitmaps of diff sequence but is there a better way to do the same in flash or rather any software which would generate this effect & then import the same in flash.

Please advise.
Thanks & Regards
Hetal

Ask alex, I think his footer has that effect... But I dont think you might actually be able to make smoke directmy with flash, since it is rather a raster/bitmap sort of effect rather than vector...
