Initial works
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
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.
Development
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 one hole, 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. 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.
