## Activities

### Goal: bring particle motions into our systems

1. What could trigger different movements, different patterns? Try mapping a external variable: either from Sidebar or any other operator into the movement.
2. How can particles have independent motion?
3. Which other offsets can be added similar to slider: OffsetZ?
