If you love of using a grid systems for every logo design you create, including marks and icons, Kareem Magdi got you covered. He shared a set of beautifully designed logomarks and the grid system behind it.
Fabio Pistoia is a designer from Milan, Italy and he shared an awesome brand identity project on his Behance profile. It's for a creative digital agency based in Milan name KIWI. There are many things to love about this project but I want to highlight the bold/blocky typeface. I have been noticing a trend perhaps with this type of treatment. Kickstarter just announced their new identity and they also employ this style. It works quite well, particularly with shorter words, like KIWI for example. Below you can see the full project including the art direction for imagery, which is not very common but it does help to create a visual identity.
