A couple of weeks ago I was wandering around the still under-construction halls of IFA in Berlin, surveying what's one of the biggest tech conferences in the world a little before it was actually ready to welcome in the public. It's a fascinating time to see this sort of event being built, not least because it really underlines just how huge an undertaking it can be to build a single stall, let alone the whole thing.
I was there with Sony, though, so while I was curious to see what else was going to be on show, there was a single tech demo that really preoccupied me. Unlike some other attendees, it was my first time seeing the tech in question, too.
