It's looking great Mike! If you could, can you post a video with the clear and the diffuser at some point? I'd like to get an idea how it looks.
Also, do you think it would be possible to have EL illuminated instruction card paper sandwiched between the diffuser and the card? Maybe even have the cards under the apron, then the diffuser, then the EL paper?
I've currently got controlled RGB lights under the triangle knockouts on my Tron tied to the ramp lights; but, I could easily see lighting up the whole apron with controlled lights.
Keep us updated on when these are ready to order.
