Well, see... I kinda want to make mine realistic. I was thinking about using fiber glass or foam board and cover it with plastic sheeting. Because this is what I want to do:
In one picture and episode it shows Sumomo sitting down on Chii's shoulder with a vid screen. One of the little circles POPS out with a cord! So.. I was kinda wanting to do that so I could have it pop out with a black extension cord wrapped on the inside that can roll in and out. Anywhoo, that's just kinda my ideal. If not ^___^ I'll gladly take your ideas!!
