Sconce Light: Hanged against the wall.



Inspired by the 4-7-8 Breathing Technique, one of  the most recognizable mindful breathing patterns.Our goal was to create a lighting fixture that was multi-purpose and interactive.

Aside from providing functional lighting this fixture aims to recreate the 4-7-8 breathing pattern.  A person interacting with this  light will be able to follow along the lighting pattern as a guide and self-regulate their breathing to reduce anxiety and stress. 

Functionality:  The bulbs generate a warm white light, and the “shade” diffuses the luminosity creating a soothing lighting environment.

This fixture  will have 3 different  lighting settings : 

OFF : A switch will place to turn on/ off the power

ON-478 : As soon as the light is turned on,  the first setting will increase and decrease brightness to recreate the breathing pattern. The light will go from a very low brightness to it’s maximum brightness. (breathing in for 4 seconds, holding the breath for 7 seconds, and exhaling for 8 seconds) 

ON - Stable pattern: At any stage of the breathing pattern the light can be stopped and hold a stable Bright lighting pattern.


Location : For this specific sample we are hoping to have our lamp hanging in the waiting room of an MRI unit. After a recent experience in an MRI room we realized that very few things can prepare a person for this event. Our hope is that patients are able to start doing the breathing exercises before they enter the room.

This fixture works as a decorative light and can easily stand on its own due to its symmetric shape.

Part of the research was testing different sample of Scoby with a variety of light sources.








Drying Scoby




Once we had the the perfect Scoby sheet we tested the light with 1 and 2 layers




















Once we had tested the code and knew it was creating the light effect we were looking for, we uploaded it to a ATtiny85. 







Overall the most challenging plant was the coding and circuit building. Thankfully we got some help!

How do physical presence function in a networked world?  The physical presence is often overseen when thinking of the networked world we live in. Flavors, smells, physical touch are all part of our daily lives in a metropolitan city. Community engagement is what helps social networks thrive. During Covid some online communities flourished . Could this possibly be  a result of  a decade and a half of using social media platforms and smartphones? To me the networked world will relay on the human social experience of proximity. For example influencers rely on their following to consume things outside of the virtual interaction but in the networked world the followers get in close proximity through consumer products, or even places that they were referred to by influencers.  The symbiotic relationship between physical and online experience will continue to feed off each other in the near future.  Create something that addresses the materiality and/or Web3 reading (...

What is the role of bias in creating technological tools? I think using technological tools is one of the easiest ways to access a larger demographic therefore it should be created by All TYPES of people. For the past 20 years we have become more and more dependent on the information we consumed and exchange in a tech environment. Bias is real and it wasn't until less than a decade ago that the conversation about bias and the impact on people life's started to become more of a central topic. Now more than ever we need to give tools to people that otherwise don't have a voice in development of said technologies. Also understanding that Bias cannot disappear from one day to another, it a long process and we need to keep the conversation and education going.
