The challenge is -adding these features without destroying fakesteak's elegance. - ## How does it work? -The `matrix` struct makes use of three 2D arrays to encode the Matrix: the -`code` array for 32-bit Unicode characters, the `rgb` array for 24-bit RGB -values of the character (foreground color), and the `shade` array for the -degree of transparency of the character to simulate the ghosting effect of old -monochrome displays.
