% Programmed in Matlab R2017a.
% You can have a glimpse of the original digital rain in the
% Matrix Movie at 1:04 (or youtube: /watch?v=3vAnuBtyEYE ).
% The original is far messier. Drops stop, start and shift rows
% additionally there are stuck letters, gaps and so on.
% This is not replicated because it makes the short loop time very obvious.
% Those features could be added in a longer video.
% The font is not correct.
% The code could be radically optimized, but hence it is intended for
% one-time use, there is no real need.

asianList = char(65393:65437); % Asian symbols; Half-width kana;
% Matlab can work with UTF-8 but M-Files are saved using ANSI. If letters are typed directly, they are lost while saving the file
