The document describes the evolution of a student's designs for posters about mathematics. The student initially planned to create an image about how math relates to modern society for high school students and parents. However, they realized the topic was too broad, so they designed a poster inviting college students to join a math club instead. Through multiple iterations, the student improved the proximity, alignment, contrast, and repetition in their designs to make the messages clearer.

1. At the beginning of this semester, I would like to design a image about
mathematics related to the modern society. The goal of that design is
introduce how mathematics related to modern society. The audience
are focus on high school students and their parents. The message I
would like to send is how mathematics influenced modern society.
After I did some design of the image, I changed my mind. I thought this
topic is so big. I would like to focus on something more detail and easy
to understand. I designed a poster about math club. The goal of this
design is inviting college students to join the math club. The audience
are college students. The message I want to send is inviting students to
join math club and doing activities together.

4. This design I improve the proximity, I put the title and subtitle together
and still not close enough. I used a picture of a boy instead of posters
without human being. Which showed that mathematics is related to
modern society, related to our life.

6. This design I improved the alignment part. The words and picture are
aligned. Compare to last design, this image organized and easy for
readers to understand.

8. This design improve the proximity of title and the subtitle, the picture and the caption. And
there is a little contrast and repetition. There is difference of colors and the repetition
between the title and the caption.

10. This design I made some repetition between the title and the body part, use different fonts
as contrast, and also use the complement colors.
