Will has the pictures with his phone, so I am unable to upload them here (he has uploaded them on his update). 

The input of our prototype is force. It is constrained by the size of the box, which limits how far you can move the string, thus limiting the amount of force you can apply.

Specific Rules for Constraint:

1. Box dimensions

2. Direction of the pull

3. Height of the string

4. Weight of the object on the string

5. Amount of paint in the device (if applicable)

6. Size of the device

I can be more precise in my process and documentation by taking more photos as well as taking more notes.

People interact with our design by pulling the string and deciding the direction of the pull, which creates a different pattern each time.
