I often say that anything can be an inspiration. Any random thing we see, sense, and experience can be used as an ingredient in a future creation. Sometimes, however, we can find even more raw materials to play with by decomposing something and focusing on specific elements.
A movie, for example, can inspire us as a complete artwork. But if we decompose it to its ingredients, we might find inspiration in a single sentence, the title design, maybe one character, and perhaps even a gesture someone does as part of a scene.
Zooming in on a specific element and them zooming out again to see the entire picture is an essential part of creative observation and a source for a whole new universe of potential fusions.
