French designer Frédéric Hamerlak developed this unique staircase that looks like it belongs in a science fiction movie. LEDs light up the plastic sheets that serve as stairs, which are connected to only the wall. They are angled horizontally in a zigzag pattern. A panel resembling a railing runs alongside them. When they light up in the darkness, the visual effect is quite stunning. You can see more photos at Home Crux.
