### Example Projects

There are many example projects using the Trail node, but here's a couple you can check out now.&#x20;

[Disciple Breeder](https://app.nodalin.xyz/project/4571ca43-c9e8-4cb0-82c3-9112484e3665)\
This is a great example of how the `front` and `worldCenter` properties can impact the visual. Feel free to tweak any of those 2 Trail nodes. Turning ***off*** the `worldCenter` creates a camera-tracking effect, while turning it ***on*** produces a more centered/flying-through/tunnel motion.&#x20;

[Rookie Crosshair](https://app.nodalin.xyz/project/d2f56f3e-8326-42f1-9cf5-a812007a0397)\
That's the example project we've used on welcome page and UI overview. Have you seen it running in real-time yet? Couple of Trail nodes are used to create the tunnel and the flames.&#x20;
