The Shuffle Play Door featured on DesignBoom includes panels that can be slid up down and sideways to reveal the door handled, secret compartments, or create a window through both sides.
This door concept from designer Wessels Moer Barjet isn’t very practical, but displays a new take on making the most of space inside a door. Just don’t slam it!
