I like overly complicated designs, designs for large stones, checkerboards, pseudobarion-ish designs, and parallel bars all over my designs. After messing around with "Sierpinski's Partial Second" and "Moar Dakka", I ended up with a design that pushes absolutely all of my buttons, and I absolutely love it. Works in materials from orthoclase to rutile (RI = 1.52 - 2.62), but should be a knockout in giant, pale CZ.
