you could do this in c4d very easily
Animate the txt however you want; you could even make it in AE and then export a video with transparent background. Go into C4D, create a plane, then use you video as a texture. Then put your plane(with text video as texture) into a cloner. then use a Plane effector with the falloff shape as: box. You can set up you Plane effector to change the direction, size, spacing of the clones.
OR
And this may be easier. Export your text as png’s with transparent background, make a cloner and put a bunch of planes in it. Create a multi-shader texure. You do this by adding a Random Effector to the cloner; turn everything off on the Random effector but have Color Mode: On. Once you do this, all you have to do is animate the Seed and it will randomly cycle through the textures on your multi-shader
I know that may be a lot but if you google anything you dont understand, there should be a quick tutorial on it.
