I've gone and made a 90 frame video intro for a Youtube series that I might or might not start. I've used the name "Grokology", as it is my domain name, and my minecraft username.
Here is an early test render of one of the frames. There have been many tweaks since then, but the effect is mainly the same.
It was created entirely with Blender 2.75, and contains 2 scenes, 3 layers, and 3 particle systems. Lighting is from far too many point lights, as well as material emission. Please feel free to comment! I will post the intro once it's done rendering, and I've had a chance to upload it.
Here is the final video. I hope you enjoy all 8 seconds! There's sound too!
