몇 가지 힌트와 덧붙임

이 프로그램은 총 97칸의 메모리를 사용하며, 12,177개의 명령으로 이루어진 메모리 초기화 부분과 3,379개의 명령으로 이루어진 루프 부분으로 나뉘어 있습니다.
실시간으로 값을 만들기 힘들다는 것 때문에 메모리 초기화 과정에서 대부분의 상수(메모리/프로그램 오프셋 포함)를 만들어 내고 사용하는 방식을 씁니다.
루프나 조건문 구현, 메모리 초기화 등을 위해서 여러 가지 테크닉을 사용했습니다. 여기에 대해서 설명하기는 귀찮으니 생략...
이 코드는 개인적으로 만든 Whirl 어셈블리 언어를 사용해서 만들어졌습니다. 여기에 대해서도 나중에...
원래 모양을 다른 걸로 만들려고 했는데 도쿠로쨩의 저주 덕분인지 만드는 중에 설사가 두 번이나 나서 포기했습니다. -_-; 코드 모양은 Whirl의 두 개의 ring을 상징하는 벤 다이어그램입니다.
이거 만들면서 음료수 두 캔이나 사 준 모 군에게 감사.
