The Kite UI or Android is just in the concept stages at the moment, although from the video below it looks amazing, and it is currently being developed by some of the guys over at the XDA forum.
As you will see in the video below, it has a lot of similarities with the HTC Sense UI, but has a different look, with similar functions.
This certainly looks very interesting, you can find out more details over at the XDA developers forum.
