I cannot believe this actually works! The guys at Make: went through all the trouble of creating a Virtual Reality headset made entirely out of edible parts (minus the lenses). All you need are the precise measurements, graham crackers, a ton of icing and a ridiculous amount of patience and you can make your own Google Cardboard headset!

I'm not sure I'd have the patience to do so, but it's cool to know I can if I wanted to.
