I’ve taken some of the ideas I’ve talked about in my blog, and used them to create an app for Google Cardboard and other similar frames (Durovis Dive, VR One, Homido and many, many others). I’ll be porting to the Oculus Rift shortly.
It’s called ImmerView, and it’s basically a modern-day Viewmaster that lets you look at a series of 3D slides. The big advantage over Viewmaster is that you can look all around you.
It’s free, and it has a small but growing library of content. You can find the app on the Play Store.
Hope you enjoy it!
