Anton D. Nagy had dug up quite the tasty morsel. A company called Tat has been designing some new and radical user interfaces for different devices ranging from Windows Mobile to Symbian and more. Although most of the designs are proof of concept designs, we hope companies will adopt some of them for their Windows Phone offerings. TAT is a Swedish company with offices in the US and Korea, “offering products and services that differentiate and enhance the user experience of portable devices.”

XDA-Developers posted some videos of the TAT interface in action for Windows Mobile. These are some fun, cool ways to unlock a device.
