Sensor Etch is a browser-based canvas app that maps tilt, mic, camera, and network speed to pen movement, brush size, ink color, and reverb in real time.
Key Takeaways
Tilt moves the pen; vertical position selects a pentatonic violin note snapped to scale.
Microphone volume and brightness control brush size and bow pressure simultaneously.
Camera feed sets ink color and violin tone: warm hues darken, cool hues brighten.
Connection speed tints the background and sizes reverb – slow yields cavernous, fast yields dry.
