Quest, the program you are talking about is called Amorphium. Metaballs are actually NOT Brycean, I'm sure you all knew that. Metaballs stem from Play's Amorphium, and were called biospheres. Biospheres, in Amorphium, are much more powerful and controllable than Bryce or Lightwave style metaballs, you can adjust the energy on Biospheres, which you can't do with metaballs in Bryce. Lightwave's metaballs are pretty cool, though... You've all seen them in action in movies like Toy Story and Finding Nemo.
