View-Master has been around since 1939, and although there's definitely an argument to be made that this is simply "3D" as opposed to "virtual reality", the usage of stereoscopic images that allowed this functionality is still how modern VR imaging works today – albeit with advanced digital rendering techniques as opposed to flat pieces of Kodachrome.
THE HYPE: Believe it or not View-Master has a current product, but instead of slotting in circular discs of film, you slot in your phone, and instead of viewing what was ostensibly a 3D postcard, you view an educational app from the likes of Discovery or National Geographic, in a virtual reality environment.
THE GRIPE: If you want the older, clickier model, you’ll need to do some eBay trawling. There are a few gems to found, but you’ll be paying much more than this for them.
