I had an idea to use my Surface Pro3 as a backlight.
Reverse the stands on the MFDs to point them forward not backwards (sits better against the Pro).
Then place the Pro3 behind and put the MFD panels on the pro either as a PDF or a windows background.
Saves on designing up new ones and always printing out / cutting.
Backlight is nice at night. Now I just need to size fully and align and hey presto, backlight MFDs.
After some playing around moved the MFD bases back to pointing back and put some non stick webbing across the bases to stop the Pro3 slipping on the stand bases.
After setting up a background and aligning the images it works really nicely.
