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.
Part of what makes this nice is that it's a handmade product of love for a family member. I think if you commoditize something like this, it loses much of its charm and even some of its purpose.
