Microsoft has shown off a new prototype - the Sphere - a touch enabled globe-shaped display, described as like the Surface's "cousin".
In the video above - which is well worth a watch - Hrvoje Benko of Microsoft Research demonstrates Sphere in action.
The device uses an internal projection and vision system to bring a spherical computer display to life.
People can touch the surface with multiple fingers and hands to manipulate photos, play games, spin a virtual globe, or watch 360-degree videos.
For now, the Sphere is sadly just a research project, with no plans to offer it as a product.
