            # About LUXBIN

            **LUXBIN** is a photonic binary language where semantic information is encoded directly in the physical properties of light.

            ## Key Concepts

            1. **Physics as Syntax**: Light parameters carry meaning
            2. **Parallel Channels**: Multiple layers of information in one photon
            3. **Non-Linear Encoding**: Not a cipher, but a genuine language

            ## Applications

            - **Assistive Technology**: Non-verbal communication
            - **Secure Communication**: Line-of-sight only, hard to intercept
            - **Extreme Environments**: Underwater, space, RF-denied zones
            - **Human-Machine Interfaces**: Direct photonic signaling

            ## Technical Details

            - **Alphabet Size**: 26 letters + 38 extended symbols
            - **Color Space**: HSL (Hue, Saturation, Lightness)
            - **Binary Base**: 6-bit indexing (64 total symbols)
            - **Grammar Layers**: Saturation, Lightness, Temporal

            ## Implementation

            - **Hardware**: ESP32 + WS2812 RGB LEDs
            - **Software**: Python encoder/decoder
            - **Perception**: Trainable by humans in ~30 minutes

            ## Status

            LUXBIN is a complete language specification ready for:
            - Hardware prototyping
            - Human perception testing
            - Standardization
            - Publication
