Some tips:
- You can change the Size if you click to "Size" and write a number in and test it out
- If you click to "Taper" it's will give it a nice effect like it's getting smaller

- With "Noise" you can make it look a cooler but not many people using it (i do)
- If Noise is on you can set up the "Wave Frequency"
