International Signal Flags, also known as International Maritime Signal Flags, are a communication tool in the maritime field. It consists of a series of different signal flags, each of which represents a specific letter, number, or meaning. Through different grouping and arrangement, these signal flags can convey various information between ships, such as the ship's identity, location, intent, etc. International signal flags are widely used around the world and are one of the important means of international maritime communication.

The meaning of each flag comes from a flag educator on Bilibili, Tie Wu. The code corresponding to each flag comes from a website about Morse code.

I'm very sorry, but I really don't know what kind of physical simulations I can do. This is a static scene. I would also be very regretful if your device becomes very slow due to the high resolution of the fonts.

But in any case, this scene is only for popular science and material purposes.
