Do you think Vault of the Iron Overlord works as a PDF? (anyone?) Given its funky map.
In the PDF (which I've just bought - thanks for the recommendations):
"Instructions for PDF Purchasers"
"This DCC module includes a map on the inside cover that actually rotates... obviously the PDF can't rotate. We have provided you with each of the rings on separate pages. You should stack these pages on top of each other, use a rotating fastener to to align them through the centre of the rings, and then clip the rings out of the paper. You will end up with the same map that is provided in the print version."
Cheers!
