Let's make a pattern, albeit a subtle one, inspired by printed circuit boards. Hell, circuit boards are the technology on which most of our world is based. 'Why?', someone asked. Damn good question really. You're suggesting a pattern based largely on horizontal and vertical lines? It will probably end up looking like a Gingham check, and we DON'T do Gingham. But the designer pushed ahead anyway. No one listens to anyone around here. And it seems she knew better!
