Chang sent me this brilliant rendition of the Armored Magazine concept. Personally, I’d pick it up for the jet pack instructions. But I think the dorky dude sticking out through the “O” needs some cross hairs centered on his forehead. :-)
More seriously, Speclit has a series of posts which touch on design in the big three, “Designer’s eye for the stodgy digests” and he’s steps up to do some cover mockups as examples. It’s interesting that he looks at the digests as digests, and thinks about how their look might be updated while continuing to respect their current form factor.
