If it's at all possible to do in Visionlab, how can a effect like this be produced? Perhaps using a certain texture with the particle engine?

Unless you are only after a still frame, this isn't going to happen with the particle engine in VisionLab. There's a slim possibility you could get decent results using the particle engine to create a single image, but the type of motion required for a fractal pattern like that is beyond the abilities of VisionLab, I suspect. For any type of decent results you would have to create textures that exhibit the characteristics of the effect in and of themselves, which will likely involve the use of a fractal generator of some sort. But to get animated results I think you are going to need some sort of particle generator with the ability to apply physics, or in some way control the interaction of the particles to create the stringy, wispy feel and movement of the effect you show.
I love the look of that type of effect, but I don't know of a way to create it in VisionLab. I think your best bet may be to start with stock footage of cigarette smoke, or some smoke that behaves similarly, then manipulate and composite it to get the look you are after.

Yes, I agree completely with your idea Axeman. Cigarette smoke may be good stock footage to achieve this effect. And I also believe smoke from a hookah, which can be more dense, would be a great possibility as well.
