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.

This is such a cool project! I live right next to a busy road and for a long time have wanted to do something like this that would count the vehicles passing. I've always been curious how many cars pass on a given day and I feel like the hardest part now adays would be getting the right camera angle so if cars are occupying all 3 lanes they aren't counted incorrectly. From there I just need to detect cars as they pass and count them.

It's really cool to see it used like this! The resulting images are really neat as well!
