Intelligence in the form of neural connectors inspires to create this collection, although it is technically challenging. It is an infinity of cells connected to each other creating thoughts, memory, knowledge. But that kind of intelligence is not enough, it is necessary to grasp the most important thing: life. Knowing how to live is also intelligence. These neural connectors thus become interpersonal connectors, and the cells can be seen as people united by empathy, the ingredient that brings us closer to family, friends and colleagues, in a word, to happiness.
