Only catch is it cannot be a flag of your own country. The study of flags is called vexillology, and it serves as an excellent lesson in design. Flag of Bavaria This flag is awesome. Look at it. Your mind wants to make it a parallelogram, not a rectangle(yeah, I know rectangles are parallelograms, but i meant like a rhombus). This illusion makes the flag look sharper, and always in motion. And yes, it looks amazing flying in the wind. The design resembles a traditional, high-contrast checkered board, but those aren't squares on the flag, they're diamonds. Those little diamonds are called lozenges. When a single lozenge is displayed, usually equilateral with points on top and bottom, it usually represents a female's coat of arms. It's interesting to note the design of this flag, originating from a coat of arms, has strange rules. There must be at least 21 lozenges on the flag, but there can be as many as you'd like, and the top-right most lozenge must be white, and an incomplete lozenge. What the?... No one really knows the origin of the colors or design. Some say they represent clouds flying in the sky, while others believe it refers to falling snow. The other Bavarian flag of two horizontal stripes, white over blue, is said to represent the beautiful contrast of the snow to bright waters. There might be more pragmatic historical reasons, or possibly the hypnotizing effect of the colors and shapes are what led it to being so effective as a coat of arms. What flags do you like?
