Days of miracles & wonder, man.
From the CNN story:
Google Cardboard looks like a set of big square goggles. Stick your iPhone inside and with the right app, you can see images in three-dimensional virtual reality.
Doctors at Nicklaus Children’s Hospital in Miami used the device to map out an operation they say they couldn’t have envisioned otherwise. […]
That’s where Google Cardboard proved advantageous over 3-D printing. The printer would have given Burke just her heart — but to access her heart surgically, he needed to be able to visualize it in context with her ribcage and other structures.
