This "한글" (Hangeul) wheel is a comprehensive exploration of the Korean writing system, featuring 94 distinct characters. It includes the modern consonants (자음) and vowels (모음) used today, such as ㄱ, ㄴ, ㄷ and ㅏ, ㅑ, ㅓ, alongside complex double consonants like ㄲ, ㄸ, ㅃ. Remarkably, it also features rare and archaic symbols from Old Korean, such as ㆁ (옛이응), ㆆ (여린히읗), and ㆍ (아래아), making it a deep dive into the history of the language.
