We like a gadget at AoB. Google Cardboard is almost the perfect gadget, being something you can use with your smartphone and doing stuff that looks impressive but isn’t actually useful. If you’ve not heard of it, Google Cardboard is a cheap alternative to virtual reality headsets made out of cardboard, usually. You can pay more if you like and get a plastic headset if you want. You slip your smartphone into this folded headset and two images, one for each eye, go through a couple of lenses to give a virtual reality experience.

The clever part is that the software uses the phone’s accelerometer, so that as you head moves so does the phone and your image shifts. It’s VR on the cheap. Techcrunch has a video showing an early version of the set.
