Entrance your audience as physical real world motion is translated into sound. Many different sensor types, source code, and online tutorials allow you to make an impact on a budget, or orchestrate computer vision controls, like a full-motion theramin. It's as simple as a drink with a maker friend to go from sketch to solution.
Make an incredibly slow piece that tracks the light from the sun. Use flashlights to control intensity. Cover sensors with your hands like a light-theramin. Discover strange sonic patterns as you use filters and different high-frequency light sources to melt your mind.
Bring sound controls to a place they've never been. Whether you're making a banana piano, a baguette saxophone, or a room full of touch pads and capacitive fields you'll find a new way to blow peoples minds and delight their senses.
Elaborate mechanical contraptions are within your reach. Use solenoids to build computer controlled drums. Build artistic backdrops and let motors and gears tell a story. Interface with the physical world and do something no one has ever thought of whether it's as stupid as a synthesizer that dispenses candy every time you play it or a robot that can draw a bow across a violin.
