Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

I haven't built it yet, but there's a homeless person that yells every night from 2am to 4am at the top of their lungs across the street. Profanities and everything.

I've been looking into directional speakers so i can kindly ask the person to quiet down without waking the neighbors up. The person in question about 200ft away
