For this exercise, I used various typefaces that I felt were different but could also flow together very well.
In the top left, I used Franklin Gothic. The letter is an uppercase "R", the image you see is a close up of where the shoulder and the leg join together, then rotated once left.
In the bottom left, I used the typeface Photina with the italic font. What you see in the image is an uppercase "Q". You see a close up the tail and the bowl, turned upside down.
In the top right, I put a lowercase "e" inside an uppercase "Q". The Q is in Futura and the e is in Didot. What you see in the image a round shape with even thickness all around (the bowl of the Q), inside you see another round shape which has an uneven thickness (the counter of the e).
In the bottom right, The images comes from where the tail and the bowl join in an uppercase "Q" in a Futura typeface.
I used slab sans serif typefaces in the top left and bottom right, to get a feel of rigid lines. In the top right and bottom left, I used more old style serif typefaces. These two classifications have completely different feels, but when you look at the lines of the letters individually they complement one another and create a piece of art that one would not expect to have gotten from letters we use everyday.
