rmatrix
Generates a 'Matrix'-like screen of falling characters in your terminal

The original cmatrix was written in C, and crashes when you wildly resize the window.
The rust version is memory-safe, and doesn't crash so easily. Both versions have comparable performance, due to the underlying use of ncurses.
