iOS N-Body Metaball Simulation

iOS n-body simulation visualized with metaballs. Physics and graphics provided by SpriteKit using Swift.

You can compare an analogous cocos2d, Objective-C version here.

Ideas / Inspiration:

* Rorschach Test
* FarCry 3 intro screen
* virus exploding cell
* functionality:
    * kill circles
    * be able to coerce nodes into a certain shape
    * probably easiest to just use polygon drawn
