Hidden Environment
Most microorganisms are known to us, but can’t be easily seen. If we approach them in a respectful way, they might just reveal their hidden world to us. Interact with this aquarium and discover the wonders of Pyrocystis Fusiformis.
Concept
Hidden Environment is an analog installation which enables the interaction between humans and microorganisms called Pyrocistis Fusiformis. These organisms are found in marine waters and have the property of glowing in the dark when disturbed. Rather than creating disturbances to make them glow in unusual ways, this installation attempts to find a respectful way in which humans can approach them.
Driven by my own memories of interacting with them at the beach, I looked at nature as inspiration for the development of this artwork. The rain is an example of a healthy disturbance that occurs naturally: it disturbs the water enough to make the organisms glow, but nourish them at the same time. In a similar fashion, humans can drip water and nutrients on them and see them glowing in return.
Structure
The materials used for this installation were the following:
- 30cm x 20cm x 20cm aquarium
- Flask with appropriate medium
- 2L Water
- 71g Red Sea Salt
- 15ml f/2 medium
- Pipettes
- Black light lamp
The installation was built around a shelf on the wall. The population of algae was put inside the aquarium, with the medium flask right next to it. Inside the flask, I put a pipette, pointing the viewers to the interaction. The room needed to be dark in order for the algae to glow, so I used a black light lamp on the floor underneath the shelf in to order to signal the installation.
The installation was open from 17h to 19h30 on the first three days of the Summaery 2019, which was the time of the day when the algae would glow the most. The users were supposed to take a few drops of the medium and drip it on top of the aquarium, so the organisms would glow. During the whole exhibition, I was next to the installation instructing the visitors on how to interact, and explaining what the project was about. I did not restrict the amount of medium each visitor could drop, but I intervened when I noticed a visitor was taking too long.

Reception
Overall, the public's reception of the installation was very positive. Almost all of the visitors were very surprised, some even impressed, when they saw the algae glowing. Many people were interested in knowing more about the organisms, such as where they could be found or how to be able to get a sample. The idea of mutual respect between humans and microorganisms was also captivating to some, which were excited about the idea that they might be somehow feeding them.
Unfortunately, I noticed that the algae populations did not recover well after the exhibition. Even two weeks after, they have not been glowing as strongly. My hypotheses are that the exposure to the open air and the hands-on interaction might have contaminated the population and hindered their health, or that their light and darkness cycles were too disturbed. Though I came up with a strong concept and tried to approach them in most respectful way I could think, I am afraid that I might have caused them more harm than good. In the end, this experience has taught me much more than I had previously thought, about the responsibility of dealing with living organisms, which have their own cycles and needs.
Development
Initial studies
My plan is to work with Pyrocystis Fusiformis, also know as Bioluminescent Algae to develop some sort of interactive media. In order to be able to have concrete ideas on which kinds of projects can be developed, I first need to learn how to grow and take care of them.
At first, I received a sample of algae from Antje Danz's stash. For that, we prepared a medium using the recipe provided by Frederic Blais-Belanger. At first, the algae were glowing very faintly in the dark, probably because they were not being given the proper care, so I also took on a caring method similar to Frederic's in order to grow them properly.
First, I put the medium with the algae inside an empty bottle I had at home.
Then, I built a simple system with a small cardboard box and a lightbulb that can be switched on and off.
They have been subject to a cycle of 12h light - 12h darkness. I still did not have the knowledge necessary to build a timer, so the activation and deactivation of the switch had to be done by hand, meaning that the cycle has had a few irregularities.
Concept development
My main interests when working with the dinoflagellates are memories from a trip I made once to a beach in Brazil. There, I was able to experience them while rubbing my feet on the wet sand. This inspired me to create a symbiotic space for humans and dinoflagellates, bringing forth the experience of the night coast as their original meeting environment. For this, I intend to work with three main elements: the sky, the sand and the sea.
The sky is the setting, it can be seen all around as a continuous dark surface that can't be interacted with. The sand is the entrance, but also the humans' natural space, where they can feel comfortable and safe. The sea is the destination, and the organisms' natural space. In between the sand and the sea, there is the wet sand, the ideal spot where humans and dinoflagellates can meet.
An important reference is the installation Tropicália by Brazilian artist Hélio Oiticica, realized in 1967 at the Museum of Modern Art, Rio de Janeiro. His work attempts to create a tropical, iconically Brazilian environment in which the people can be reminded of the experience of walking through the hills and favelas of Rio de Janeiro.
Summaery Proposal
- Complete: /Summaery 2019
The idea is to create a hidden environment that can be discovered by interacting with bioluminescent Algae. The project’s main object is a transparent tank filled with the algae in the appropriate medium, as part of a miniature artificial environment. The box will be placed inside a dark chamber so that when a person pours the appropriate medium on the box through a dripping mechanism, the algae will glow and reveal the inner environment.
The idea of dripping water on the tank comes mainly from the idea of rain as a natural phenomena that could familiar to both humans and algae. When the visitor pours medium on top of the population, they are also nourishing them with new nutrients, renewing their environment. It is also an attempt to interact with the algae in a more respectful and gentle way, unlike many installations that attempt to make them glow through unusual means, such as sound vibration. With this sort of interaction, the viewers can experience their beauty without disturbing them too much, and in a way in which they can glow for longer.
Execution
Some attempts to make a dripping mechanism on top of the aquarium were made. These prototypes featured a lid with small holes to make the water drip, instead of pouring. The idea here was to simulate rain, as the water would drip through many holes randomly, and slowly. The schematics below illustrate how people are supposed to interact with the tank. Inside the tank, there is an algae population; beside it, a bottle filled with the appropiate medium, without algae.
When testing it with a real model, instead of dripping through the many holes, though, the water would drip through only a few holes, in a fast pace. Another problem is that the mechanism on top would distract the view of the environment itself, as the surface was not visible from above.
Because of that, the whole project was simpliflied. The lid was replace by the usage of lab pipettes, used for dripping liquids onto containers in a controlled manner, as seen in the schematics below. This way, the viewers will have more restricted amounts of liquid to drip, but also more liberty to choose where in the tank they would like to do it.
