Design 201 is a variation of Design 1 (1950), a more complex wall. “Light hitting the screen from the front," Hauer says in his book, "accentuates the continuous, meandering linear patterns that traverse it apparently infinitely; much like the continuo in baroque music." But when it is backlit, the screen interacts with light in such a way that the complex spaces embedded throughout seem to glow from within and take on a life of their own. Both aspects are dynamically intriguing.
