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. The symbols vary from letters to animals including squirrel and elephants to other more abstract shapes. Personally, I like the use of this technique to make sure that the form is optically balanced, however, I also think it's not needed all the time. It might add too much rigidity to the design.
