Re: cardboard artistry.... Let's not get carried away, now. It's pretty easy to look good at 640x480!
I'll look into that wood glue idea.
The big issue isn't really the outside surfaces, it's the edges - the corrugation is perfect for wicking up any water that touches it, like a thirsty camel at an oasis.
Also, my plan all along has been to encapsulate the thing in plastic wrap.
This one isn't going to end up in the recycling bin!
