In the portrait, the balloon represents an emotional state. The pump represents society in general. Society pumps words, expectations, and ideas into one's head. A certain amount is healthy, but too much will make the balloon pop. The red colour of the balloon represents The broken light bulb represents a loss of interest in intellectual activity in some people as a result. It also represents the ability of society to burn people out with excess stress. The smoke is from the filament lightbulb due to the lack of a vacuum and does NOT represent any kind of drug in any way, as some of my classmates suggested. Any sort of similarity was entirely unintentional.
