Matrix rain code

Hi guys!
I’m new to the study.

I’m trying to do, "matrix rain code " as in the film, from the logo, but I have something which problems:

  1. I can not do that the first element was white, and the latter gradually disappeared as the video. (
  2. I do not understand how to make more than one column of the rain.
    Can somebody help me?

Well, I hope this could help you to find a solution with vvvv, in patch.
I had some fun patching this. It’s very basic, but it can shed some light, hopefully. (6.6 kB)
