If you remember Zappar's Adventure Suit interactive book that I reviewed back in April this year, you may be interested in their latest offerings called ZapBox 2.0 and ZapWorks Studio!
To showcase  the types of experiences you can create with ZapWorks Studio, the makers have come up with Zap-in-a-box, which is essentially a fold-out cardboard viewer similar to Google cardboard that comes with cool immersive virtual reality experiences.
All you need to do is download the Zappar app and scan the zapcode included with Zap-in-a-box. You can use Zap-in-a-box headset viewer with other Google Cardboard apps by simply pairing the Google apps with Zap-in-a-box via the code below.
You can also make your own zap experiences by signing up for ZapWorks free trial and use their software for 30 days free. Once you create a zap experience, you can update it whenever you want and republish it in real time.
