Chrodal Distance

Type: sound / spatial installation
Partner: Sylvan Zheng
Year: 2019

#ableton, maxmsp, cnc, rhino,
wood fabrication, bluetooth connection

A sound installation that explores the relationship between two people by connecting the physical act of pulling to music.

As the two participants negotiate their mutual physical equilibrium music responds to the surges in tension, releases, and twists highlighting the nature of their relationship. While the installation affords this personal experience to the participants it also serves as a performance for a larger audience to engage with.

Two wooden handles hang suspended at chest height, connected to each other with a simple band.

We invite participants to explore the subtle musical shifts in tone and harmonic texture throughout the varying positions and tensions afforded by the installation.


Everything in this world forms its own state of equilibrium. The form is defined by the result of finding a balance of multiple forces surrounding them.

Interactivity happens before the conversation: such ‘feeling’ that instantly happens when they touch or see the object. We wanted to bring that idea into a installation where relationship could be visualized via different medium.


In the process of developing this installation, we focused on the idea of finding balance through negotiating physical equilibrium. This handle was to stimulate the tangible interaction of physical forces. The elastic band gives a playfulness of the interactivity, while functions well enough as a medium to convey the pulling forces.

Before playing the instrument, the participants are given simple instruction to slowly pull on the handles. The linearity of both handles is read as a part of the vertical string of the whole installaion. This gives access to the participants to come in and start playing by just grabbing suspended handles. And as the participants explore the tension and the music, the string creates different shapes and scapes around the center of the suspension.


(from left to right: a first step to find the right volume, reduced size with parts, a rhino model)
The handle is composed of a load cell, an arduino, a hook, and a LiPo battery, and a switch. The wood is separed into top and bottom parts using tension fit. CNC is used to carve out the wood. The main challenge was to make a design that that could be as ergonomic and light as possible so that it could be hanged using tension of the string.

Blur Clock

A clock that is only legible when you are looking at it.

The clock is inspired by The Order Of Time by Carlo Rovelli, who theorizes that time as we usually imagine it only exists because of a “blurred macroscopic perspective of the world that we encounter as human beings [and that] the distinction between past and future is tied to this blurring and would disappear if we were able to see the microscopic molecular activity of the world.”*.

* Valerie Thompson - Science Magazine  A quantum physicist reveals why time is not as simple as it seems

 Along with the thought that humans create time itself, we are tying in quantum mechanics and the idea that nothing exists in a determinate state until an interaction occurs or a measurement is taken. In our clock, the time is indeterminate and blurred until we measure (by looking at the clock) which causes an exact time to be visible.


In addition to Blur Clock, a sun clock presents another way to look at time, which is to tell the time by the sun’s location. To actuate the idea, we built a simple app to place the sun based on the zip code entered, using sun rise - sun set time requested from OpenCage api. 


The clock consists of a Raspberry pi computer connected to a stepper motor, camera, and led matrix panel. Using OpenCV (machine learning / artificial intelligence) eye tracking, the clock knows when your eyes are present and open and triggers the motor to push the screen closer to the dichroic diffusion panel. When you look away, the led matrix recedes from view.

The box is made from 10 pieces of CNC’ed PVC sheet finely sanded and finished. As you walk by the clock the face and colors of the time or sun change color.

Shadow Box

Type: Interactive artwork

Year: 2019

#arduino, laser cutting

A shadow puppertry box where the interactivity is conducted by the gaze of the viewer.

In the house of nine rooms, nine incoherent scenes are taking place.
As you move on your attention, you create your own interpretation of the cinematic experience.

Inspired by brownstone houses in Brooklyn, I always imagined and was fascinated by the idea that different stories could be happening in each familiar looking houses. The telescopic view is a analogy of our subjective perspective that makes up our perception of the world.

By looking into a peephole, the audience is exposed to nine disparate scenes. While spectators move on to the different scenes, each will build their own narratives. 
The box is made of three components:
1. An outer box with sub led light attached inside to give an atomsphere of the house.
2. An accelerometer and arduino uno lighting up each rooms accordingly to the direction of each cells.
3. Aack piece with reflective tape to concentrate light source, two power supplies.
