Wow, this is a very interesting interface that comes from TAT. Though it may not lead to the highest level of productivity, it sure is visually stunning, and even quite intuitive. There aren’t any menus to speak of – everything is visual. Will we ever see this interface on a phone? Probably not in this form, as it seems to be just a proof of concept for the new Texas Instruments platform:

This 3D demo was developed by TAT for Mobile World Congress 2009 in cooperation with Texas Instruments. Foldout UI is a Cascades implementation on the Texas Instruments OMAP3430 platform, using Open GL|ES 2.0 and hardware acceleration. The demo shows a unique utilization of 3D in combination with touch input. It challenges traditional UI paradigms with its flip-through navigation and foldout design. Realistic materials, physics, shaders and other effects give a real-life experience to the GUI, and the input gestures demonstrate how touch interfaces can develop beyond the tap.

And while we’re talking about TAT, take a look at their YouTube Channel…they have several other really cool interface concepts. Via Derek Snyder’s blog.
