This anonymous designer baked banana bread and used an engineering design process (see Dubberly) to make their postcard representation. Each horizontal line is a segment of the design process with time running from left to right, and each symbol is an emotion. For example, the second line has one circle at the front, meaning that during the analysis portion of the process, the anonymous designer felt calm at the start. See the back of the postcard for the key and other details!
