Here's a great article to bookmark. At Just Creative Design
Jacob Cass interviews Jeff Fisher of Logomotives. There's a little bit of background info on Jeff (award-winning identity designer, writer, lecturer) but then the interview moves right into the logo design process -- what others do, what Jeff does differently, some great stories of jobs gone wrong, discussion of Jeff's familiar LogoMotives logo, some of Jeff's favorite corporate logo design -- including so-called "rule-breakers," and advice to aspiring logo designers. Long but good read. And Jacob has highlighted a lot of the key concepts covered in the
article to make it easier to skim.
