Swift 3D "particle" effect

I am currently working on a broadcast motion graphics piece using Swift as the primary 3D modeling and animation tool, with post-production in Flash and finally converted into a broadcast video format. I wanted a particle like effect, however since Swift lacks a scripting language, it had to be done the old fashion way...by hand. The below shots give an example of the effect. The actual piece is 720x540 and will be approx. 400 frames at 30fps, so is too large to put online, however I will see about getting a web friendly version once the deadline has been met.

While it looks pretty busy, the scene is actually only composed of around 88,443 edges (55,193 polygons).
