The torrent of lime-green characters from the now iconic beginning of The Matrix does have a meaning…
What looks like indecipherable code is actually a jumble of Japanese characters: hiragana, katakana, and kanji.
The man responsible for what’s also known as Matrix’s “digital rain” is Simon Whiteley, who worked as a production designer on the Wachowski Bros.’ film. In an interview, he revealed that the source of the code was none other than a batch of his Japanese wife’s cookbooks.
“I like to tell everybody that The Matrix’s code is made out of Japanese sushi recipes”.
