Looks really cool.
My one twist would be to print the screens on transparency paper to make them jump out a bit more, maybe with a foil background.
It would be nifty to have the screen placement on the fold model for people who want to do that (or who want to go one step further and make the screens illuminated).
I don't think I'd mess with the illumination thing... But I MIGHT be tempted to make them illuminated from a backlight, ala the way many TF's eyes light up.
... Y'Know, I take it all back. Illumination would be barely worth it considering the option there are nowaways for keychain picture storage and digital picture frames.
My inner overacheiver wishes I had the spare cash to get those digital picture frames for all the panels. I've seen keychain sized ones for around $15 and I think you can actually get ones that display short video for around $60 or so.
How awesome would that be to see this thing with rotating caches of images, illumination and video on the main screen? (Though for that, you really want a nice video editing suite.)
It would be cheaper than a Botcon exclusive set to put the whole thing together though and IMHO much cooler. Could you imagine this thing with Optimus vs. Megatron from Transformers the Movie playing in a cycle on the viewscreen?
