Wisp
Like most all Blender-related stuff, it all started with a Cube. I fired up Blender 2.63, created a few objects, and decided to play around with the Smoke Modifier and a few days later, I realized I was already into it so much I can't stop the test and decided to give it some final feel to it.
This is my second (if I can remember well) serious test with Blender's smoke modifier, the first one, which is now two years old, you can watch at
