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 live on the flight path of a busy airport (Toronto) and have always wondered what type of aircrafts they are as they fly above me.

So, I made a "Plane Above Me" app that listens to airplane sound. Once detected, it polls data from flight APIs and read out the flight info and aircraft data.

In other words, it's my little "Flight Announcer".

British Airways had a famous advertising campaign that did something similar. If I remember correctly they used a digital billboard somewhere in London that showed a little boy pointing to the sky. The text refreshed throughout the day to display the details of the flight passing overhead.
