Design Police: Visual Enforcement Kit
Like those little stickies that say "Sign Here," the witty Visual Enforcement Kit points out (with excruciating detail) what needs attention, in this case in the world of 2D design. For anyone who's faced more than their share of design that needs help, the downloadable pdfs provide handy pre-printed critiques like, "Severe lack of creativity" and "Kern this!" We particularly like "Hire a copywriter" and "Do not get en and em dashes mixed up."
While the stickers might make crits easier (if you were to actually use them), they probably won't make them much less painful. Either way, they're sure to get a chuckle from any frustrated designer or art director faced with the predictable set of errors and equally predictable responses.
