Not impossible - Inventing the holographic projector: Will Tamblyn and Gavin Smith at TEDxAdelaide

Will Tamblyn and Gavin Smith are obsessed by all things technical. They like taking things to pieces and putting them back together in different ways. They are self-taught in many areas of design, manufacture, programming and visualisation -- and over the past four years they have been trying to turn their crazy scribblings and random thoughts into something real and exciting. What's now called the Voxiebox was conceived after a few beers, standing in the shed wondering what to make. The conversation went something like this: Gav -- "What do you reckon we should make?" Will -- "How about a robot with a holographic projector for a head?" Gav -- "Hmm, that sounds impossible, holographic projectors don't exist yet." Will -- "Exactly, so let's build one." Gav -- "Yeah, ok" It turns out it wasn't impossible, just really, really difficult. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
