{
    sensor = new upm::LoL();
    signal(SIGINT, sig_handler);

    unsigned char *buffer;
    //buffer = sensor->getFramebuffer();
    int x = 0, y = 0;
    while (!is_running) {
        sensor->setPixel(x, y, !(sensor->getPixel(x, y)));
        if (++x == 13) { x = 0; y++; }
        if (y == 9) y = 0;
        usleep(10000);
    }
