Here's how to experience the next generation of media for just $20 - and where to find the best immersive content for free

Samsung has just released its Gear VR, the first real consumer headset for virtual reality, and the reviews are stellar. But if you don't have one of the few smartphones that it supports (Galaxy S6, Note 5, etc.), or the money to spend, the Gear VR hype can just be frustrating.

But luckily there is a way to get set up with a basic virtual reality experience for only $20: Google Cardboard.

Google Cardboard headsets are basic virtual reality goggles made out of cardboard - and they actually work. All you have to do is velcro your smartphone in place, and you're ready to go (it works with both iPhone and Android). You can then look and move around while inside spherical 3D videos or games.

And if you've never experienced that, it can be jaw-dropping.

While the quality on Google Cardboard will not be as good as on something like the Gear VR - which features highly accurate head-tracking sensors powered by the team behind the Oculus Rift - the platform will certainly give you a novel experience, and has some prominent supporters. In fact, The New York Times recently sent all its Sunday print edition subscribers a pair. The Times wants people to be able to watch all its new virtual reality content.

But if you're not a Times subscriber, you can snag a Google Cardboard for only around $20 from several manufacturers. I Am Cardboard is a reliable one ($19.99), but there are many most listed here.

Once you have the Cardboard, it's time to find virtual reality videos and games.

We've selected the best ones for you. Here are 10 free Google Cardboard apps that will give you an eye-opening introduction to virtual reality.
