Google's Just A Line app lets you doodle with your friends in AR

There are plenty of apps out there that let you draw little doodles on photos or even videos. But the doodles are just an overlay on top of the footage. What if you could draw doodles that appear in 3D space, allowing you and your friends to move around them?

That’s what Just A Line does. You can doodle with your finger on your video footage in real time. Once you’ve recorded the footage, you can easily share it with the world. There’s a lot of opportunities here to make some amusing five-second clips of people interacting with doodles in strange ways (keep it clean, folks).

The new app came out of the Google Experiments project, in which Google encourages coders to experiment with new technologies just for the heck of it. Anyone can create and submit an experiment, and if Google likes it, the project gets featured on the Experiments website.

As of right now, there’s not much else to the app besides AR doodling. However, it’s a lot of fun and could be put to further use somewhere down the line. Get it? Line?

Anyway, check it out for yourself by downloading the free app using the button below.
