Not so far! The intersecting angles in the first really caught my eye. It's amazing how our brain is constantly looking for patterns, even when we are thinking of something completely different. I was contemplating how few people whistle these days, and I remembered being a young child, fascinated by an old man in our street who would whistle very loudly and intricately for the whole world to hear. And then my mind saw the angles, and immediately I was in a different world. The brain - yes, even mine! - is an extraordinary thing.
