Demo of how to sample the camera texture and map it to particles.
Features include:
- per-particle texture scaling
- world space mapping
- fit plane type emitter to screen size
- fit particle to screen size
- determine distance between particle and camera

- Master is an aggregate of features that compose my preferred configuration
- Particle fit2screen will give you a bigass particle that fits the whole screen
- Camera distance assigns color to each particle based on distance from camera.
You may need to import DeviceMotion module in script to activate gyro support on device. For some reason this capability isn't automatically added for world space emitters.
