    works perfect, seen this before had to give it a try and it was awesome using cmatrix -b

  • KZL Jan 18, 2018 @ 14:06

    cmatrix on a higher speed is very CPU intensive (written in its manual too) and so a great tool to stress the processor

  • Tracer Feb 7, 2018 @ 12:00

    This is simply amazing!

    I am neo and I like this curses-based scrolling ‘Matrix’-like screen <3
