Has anyone tried using a white acrylic sheet behind a marquee?

I was thinking of using a piece of white acrylic behind the marquee graphic to help diffuse the light and give it a more consistent look.

Has anyone tried this? What were the results?
The only negative I could see is that it might wash out the marquee graphic.

I use a white acrylic diffuser behind my marquee. It does create a more even spread of light. I used Cold Cathode tubes for my marquee. 2 of them approx 8 cm apart. You cant see the individual tubes just a constant illumination. Didn't have any problem washing out the graphics. It's not nearly as bright as a fluresent though. Heres a vid of it in action.

You can use a diffuser panel from a fluorescent light... easy to cut to size and only a few bucks at your big box hardware store.

I used a black transparency behind mine with cut outs to make certain areas more bright.  Look at the text and the eyes.  Those areas pop more.  Those areas were left clear and the rest is dark.

That looks pretty good.
