I like the concept and it's certainly something I would use. A personal preference is that I wish the raster images were a little higher resolution, which if you're using illustrator might just be a matter of adjusting the settings on saving or exporting as a PDF. It's mostly because I like to print out the stuff I use for games and such. 

Small nitpick though, other than that I like the swinging coffin mechanic and the fact that it's black and white (since when I print stuff out at kinkos more B&W pages means I can print stuff out a bit more affordably)
