I have also tested the text on a screen billboard in an image of St Pancras station. I wanted to make the text scroll fast and slow randomly so it can attract people’s interest, sometimes it could stop on certain phrases etc although this seems like a failed experiment. It could be better. Feedback given from this experiment was that the place where this picture was taken looks really busy so people won’t look at it, especially when the text scrolls so fast. Probably some phrases would better, instead of the whole text.
