+## How to Play!
+Download [processing](https://processing.org/download/) (for free) and run this script inside of it.
+
+Zoom out a sufficient amount.
+Slow down and speed up time until you see the points align.
+#### Controls:
+* `+` | `-` - zoom in / out.
+* `>` | `<` - speed up / down.
+* `shift` + `>` | `<` - speed up / down (more).
+* `/` - set speed to `0`
+* ` ` (spacebar) takes a snapshot and saves it in `./frames/`.
+* arrow keys to move.
