Recently, I stumbled across this awesome Design Police Kit which allows you (yes, you!) to become your very own police-person. Or whatever. Anyway, it’s interesting because, while it has a functional purpose, the kit also helps teach you what to look out for in your own designs. I’d recommend taking the kit to your own designs before rounds of editing.
Download the entire kit at the Design Police Headquarters.

sometimes some proper stickers can be useful in the real life!
disgusted by bad design on the street? obsession with perfection or more simply…good taste? this designer couldn’t stand anymore.
