Doing a Digital Water Curtain Effect

I am trying to make a digital water curtain effect, I want to control the opening time of the solenoid valve by scanning text or pictures, Now I use Ramp TOP, Text TOP, Switch TOP。 I don’t know the follow-up operation settings, I hope some friends can give some help and suggestions.

If you’re wanting to create an effect on the text, you should use a multiply TOP as opposed to a switch. What you could do is multiply the text by a moving ramp TOP, maybe throw in a displace TOP to get a liquid effect, and then it will look like it’s moving across the text.
