// random.rs - Sets each pixel on a Blinkt! board to a random RGB value in a loop.
//
// Interrupting the process by pressing Ctrl-C causes the application to exit
// immediately without clearing the pixels. Check out the solid_signals.rs
// example to learn how to properly handle incoming signals to prevent an
// abnormal termination.
