Up until a few years ago, VR was a sci-fi pipe dream. Now it can be experienced by anyone with a smart phone. Today's VR goggles are cheap and easy to use. The image above shows Eline wearing one of the most popular units: the Samsung Gear VR, which is basically just a casing for a Samsung Galaxy Note smart phone. Pop your Note into the casing, pull the goggles onto your eyes, and the smartphone’s screen acts as your doorway to another world. Google Cardboard uses a cardboard casing to the same effect, making VR even cheaper and more accessible.
