A machine that creates a visual representation of non-visual forces, in this case sound waves by shaking a piece of paper with salt on it. Based on the frequency, the salt forms different patterns. 

2. Brief: 

Salt Speaker was designed to create a visual representation of non-visual forces, sound waves in this case. The machine was developed through a series of prototypes. Initially, a pendulum marked up paper below, activated by an initial push. It moved from this to a speaker attached to a device via an aux cord, which vibrates and forms patterns with salt on a piece of paper above. It works best when used with set frequencies (songs don't work very well). 

The goal of this studio was to visualize non visual forces. Our goal was to try to use mainly analog technologies, but we were allowed some wiggle room when it came to using digital technology, as we used a speaker which is wired to a computer or phone.

Our project visualizes non visual forces by moving a string with an ink dropper attached. When forces are applied to the top of the string, and are amplified by a tin can in which the string resides, moving the string below.

We designed our project to visualize non visual forces. Our project is for anyone, and we made it through a series of prototypes. Initially, we used just a pendulum to mark up paper below. We moved from this to using a tin can surrounding the string, and we hit this can with a tuning fork. This amplifies the force, and moves the string. At the end of the string, we have a dropper with the rubber part removed, so ink can drip onto the paper one drip at a time.
