Researchers at Hasselt University iMinds in Belgium have built a shape-shifting prototype phone. Called Paddle, it's design is based on 3-D Rubik’s Magic Puzzle, a loop of 8 squares that can currently fold into 15 different iterations. It unfolds for a map, scrolls a list in a circular loop, or flips "pages" for viewing album photos.
