Customizable features:
- Speed
- Fog density (how far is the tunnel visible)
- Brightness
- Camera aspect
- Bends sharpness (how sharp are the bends)
- Bends length (how long are the bends)
- Bends probability (how often are there bends)
- Maximal frames per second – (less fps - lower energy usage, more fps - smoother animation)
