To have just one, means you cannot divide again. A monad is just that. It is one thing. A monad can be used as a simple object and when repeated, can create more complicated structures. When you use this method to design something, the space that the structure makes is a representation of the solid space made up of the individual monad its self.
The picture above is a shot of my monads. The individual monad is a diamond shape with a large cut down the middle and a notch on each side. With this shape I created the two identical structures seen in the picture. Those themselves now become monads. Technically, by the definition above, the two objects connected in the picture, are not monads themselves. They can be divided very easily into the more simple diamond shapes that were originally cut out.
Other students used origami, different scales of the same shape, and 3 dimensional objects that interlock. The challenge I cam up with is in how the monads connect to each other. Creating a simple notch in each monad limits how each shape can be connected. It actually kind of creates a 2 directional method for a 3 dimensional object. So I spent a lot of time thinking about what kind of “notches” I could add to my original solid diamond. I chose the long cut down the middle because it allowed each monad to infinitely fit into a different position, inside of each other even though each object is made of strait edges versus circles.
