Make a glitch material effect for UI

Hi all,

I am trying to make my UI look like a projection onto the inside of a visor. I am aware of using retainer boxes to add effect materials and I have already added a parabola distortion effect to make it look like the UI is on a curved surface. I have also added some UV distortion by following a tutorial. But I also want to add some glitch effects in the colour, not just the UVs. I want some slight glitchy effects that make it look like a projection. I have been fiddling around with materials but I’m not great with them. Could anyone point me to an existing material like this, a tutorial or just give me some advice on how to make something that looks like a projection?
