A tile is a slab of fired clay for covering roofs or lining walls and floors. Through the ages, human creativity has seen many new ideas to shape this basic need. Patterns of repetitive shapes may exist in triangular fashions, hexagonal, and many other kinds. Ingenious people from Pythagoras to M.C. Escher have given us much to wonder about.
This line of words covers the current tile over at least a couple of square centimeters, which should be plenty to serve as an example of how readable the text remains when projected over such image. Since this is the sole purpose of the text, it might as well end with this word.
