Each element posters' design employs indexical images, graphics, and typography to convey their meaning within the system of the periodic table. For example, the element poster: Oxygen, uses a micro photograph of a plant's leaf, as reference to the plant's photosynthesis, a process that produces the element of oxygen.
The element poster for Carbon references the human hand. This indexical image refrences Carbon as the building block for the human body. Both posters, as a whole, create a system for visualizing the periodic table, through the use of typography, iconography, and indexical images. Therefore, a theme and variation of this visual system produces a poster for every element within the periodic table, from Actinium to Zirconium.
