I've been working on this one for awhile myself. I haven't gotten very far into it, really...just getting the paper aged, and the mat painted. It's just been a matter of finding the time, the engergy and the patients to work on it. However, I have managed to keep my 5-year old daughter from getting at it with her crayons, so that's a bonus.
Anyway, I can't quiet figure out how the spinning map could possibly be a rolling map, too...I mean, even with the circles all being connected in the center with a pin or something, how can they spin clockwise and counterclockwise and still be rolled up, all the while remaining nice and flat? My guess is that they used a bit of prop trickery to pull that off, sort of like that locket in "The Illusionist".
I'm still working on my map, though...it's coming along slowly but surely. I've decided to draw the whole thing by hand and staying off the computer for it, except to download any reference pics.
