I love working with vector art; it allows very precise control. The image that I made and used to create this pattern (the five letter word) was carefully calculated to be as mathematically perfect as I could figure it: Every line yout see is the exact same thickness, the same distance apart from its neighbor and every radius is calculated to nest perfectly within the last. The spaces you see between the parallel lines and matching curves are also the same thickness as the lines and curves themselves.
So, can you see the hidden five letter word? I’m off to bed now before I go cross-eyed!
