Queen guitarist Brian May launches a Google Cardboard competitor 

Even rock legends can catch the virtual reality bug. Today, Queen’s Brian May announced Owl VR, his own take on the Google Cardboard-style headset, at an event in London. 

The plastic device, which clings to any smartphone, is based on the concept of stereophotography, a way of pairing of two “stereo” images that was invented in the 1830s.  Unlike Google Cardboard, the design of the Owl VR viewer is open, rather than being a light-tight box.  

The new low-cost VR gadget ships in mid-June.
