The YouTube phenomenon (17 million views and counting) gave us a glimpse of the world of tomorrow and was so attractive because it all seemed so possible, as many of the technologies on show have already been developed and are just waiting to hit our homes and streets.
And now we've had to spend another 5 or so minutes with our jaw on the floor as A Day Made of Glass 2 has been released.
According to its makers, the sequel "extends the ideas, applications, and interfaces introduced in the original video into new arenas – including healthcare and education – continuing the story of how highly engineered glass, with companion technologies, will help shape our world".
According to us, it's just bloomin' brilliant. How can you not love a bit of AR Jurassic Park action, or the fact that a doctor can literally drag a patient's brain around?
There's also an extended version of the video that gives a bit of extra detail on the technologies used in the action.
Mind-blowing stuff, we're sure you'll agree.
