Showing my age here but the following video shows the view-master I remember from my childhood
It’s nice to see Cadbury have a 2012 version of the View-Master which they are caling the Joyviewmaster.
The Cadbury Joyviewmaster shows slides from Joyville the Cadbury’s London 2012 House which will be set up on Hyde Park for the London Olympics.
From what I can gather it has 42 Cadbury and Olympic themed slides further info can be found on the Cadbury UK Google+ Page
