Yep, it’s The Tangent, a landmark facade on the headquarters of the Hyundai Development Corporation near the COEX in Samseong-dong.
I guess what you think of it depends on what you think of its architect, Daniel Libeskind. Or more to the point, it depends on what you think of Daniel Libeskind and rhetoric like this:
The Tangent is a project that is about the relationship between the ever changing circle of nature and the straight line of technology. In the contact between the circle and the line, one can see the meeting between the wheel and its path. Through their mutual engagement, nature gives reality to machines and machines extend nature to new and unknown horizons.
I designed this unusual image for Hyundai to show that the straight line of technology and ecological sustainable future can become a positive vector in space and in travel. The wheel and the line relate to the tension and sensitivity of one to the other.
Not everybody is impressed, but it works for some folk, I suppose.
