BlackBerry 10 & Windows Phone UI inspired by TAT
Was just going through some of the videos uploaded by TAT on youtube and I came across some concept UI videos.
Acute - YouTube
This one is called the "Acute" and looks to me that it has inspired the Windows Phone UI.
Business UI - YouTube
This one is called the "Business" and looks to resemble some of the UI elements from the BlackBerry 10 preview (whatever we've seen so far).
I don't really have facts to back it up :o But you can go ahead and check it out for yourself :)
