It's official: we're well on the way to a true 3D display. This one, called Spheree, is the work of a team of researchers working together from the University of Sao Paulo, Brazil, and the University of British Columbia, Canada, and it's mesmerising to behold. Like its name suggests, it's in the shape of a translucent sphere; inside, the viewer can see animations and images that appear to float in the centre; as the viewer moves around, they can see other sides of the object as their perspective changes. And it's all based on optical illusion. Packed inside the Spheree are multiple mini-projectors, which shine the images onto the interior surface of the sphere. Special software designed by the team blends the projector images together for a single, seamless image.
