I had fun playing with the app Just a Line. It lets you film a short clip and draw over the top of it. If you move the camera while drawing, your doodle becomes 3D. Apparently you can share the augmented reality fun if you pair your phone with another one, but sadly the app wasn’t available on my son’s Sony Experia. So instead of enjoying a virtual game of noughts and crosses, I sat on his top bunk and played with my cat instead. Similarly to Pokemon Go, this app seemed to make my phone very hot and drain the battery very quickly, so I ended up deleting it. Which is a shame as it was good fun. Even more of a shame is WordPress won’t let me upload the cat videos I made, so you’ll just have to use your imagination. Or contact me and I’ll send you them. Or, you know, get a life.
