Concept from Korean designer Sungho Lee: Intuitively, I love it! How clever! I want to make a bunch of my own—as I imagine Mr. Lee did—by cutting up some paper clips, clipping the leads on a bunch of LEDs, and soldering the one to the other.
RL The pin from which I grabbed this chair/ladder combo points to a site that no longer hosts the information. However, I can't help but love the design. Flipped towards the right and it's a chair, flipped opposite, it's a step ladder.
