OpenScad MetaBalls!

Well, it's inevitable that there will be 3D printable analogs to just about every graphics primitive/technique in existance today.

This thing is an exploration in metaball creation using OpenScad. What's a metaball? In graphics, particularly ray-tracing, they're blobby objects. That's how you get a nice muscular rendering over a skeleton, for example.

Although be a fairly straight forward technique, they are very computationally expensive. This implementation is the most rudimentary I
