    Its a laser projector when you talk into it it vibrates the balloon which vibrates the mirror and the laser shoots on the mirror

    What is that? And what does it do?

    Interresting application. I'm guessing that there's a mirror vibrating or rotating in the blue box? What power source are you using? And are the patterns random or do you have some means of influencing/altering them?
