Perfect! I've enhanced the 3D face on the third screen with:

## 🎨 3D Depth Enhancements:

### Face Improvements:
1. **Multiple depth layers** - 3 layers of the face outline (back, middle, front) with varying opacity
2. **Inner mesh lines** - Connect key points to the center, creating a wireframe depth effect
3. **Cheekbone definition** - Added lines showing facial structure
4. **Eye sockets** - Subtle outer ellipses give eyes more depth
5. **Larger tracking points** - More visible facial landmarks that pulse
6. **Nose bridge** - Extended from forehead to tip
7. **Eyebrow definition** - More prominent and shaped
8. **Mouth depth** - Double-layered for 3D effect

### Additional Orbital Rings:
- **4 orbital rings** now instead of 1, at different sizes and opacities
- Creates a layered depth effect around the entire scene
- **Depth rings around the face** - 3 animated elliptical rings that pulse

### 🎥 Orbiting Cameras:
- **6 camera icons** orbiting the face in 3D space
- Camera icons rotate continuously on their own orbit
- Scale and fade based on depth (closer = larger/brighter)
- Independent animation loop using `requestAnimationFrame`

The face now looks much more 3D with proper depth perception, the multiple rings create a layered atmosphere, and the orbiting cameras add dynamic movement to show the tracking system in action! 🚀
