At the center of the room will be a spherical mirror "projector", on which the ''Physarum Polycephalum'' will grow. A shadow of the growing Physarum will be cast upon the walls of the room. The room will be otherwise empty. Access to the room will be achieved via a door which will blend seamlessly with the surrounding walls. Furthermore, visitors can only enter the room one by one, in order to intensify the intimacy and intimidation between the Slime Mold and the visitor. | ||

To ensure that the shadow casted is sharp enough, a strong, linear light source will be placed | To ensure that the shadow casted is sharp enough, a strong, linear light source will be placed in front of a spherical mirror. The light source will be covered with black cardboard which will have a small opening. A petri dish with ''Physarum Polycephalum'' will be placed in front of the light. The agar medium inside the dish will be prepared to be as thin and transparent as possible to ensure a clear projection. The projector will be put high up in the room. Furthermore, the room will only be lit up when a visitor enters room, in order to not disturb the Slime Mold with too much light and establish a healthy environment for its growth. | ||

Thus, I will be amplifying the Physarum's size artificially. My spherical Ikea table lamp will hopefully suffice to do this. The resulting projection will only be a shadow across the walls of my room, however I believe shadows can be more intimidating than the thing itself and intimidation is something that I believe contributes to hierarchical formations. Furthermore, with a colored LED, the result also has the potential to be aesthetically pleasing. | Thus, I will be amplifying the Physarum's size artificially.

''Rethinking:'' | |||
I have my doubts about the blurriness of the shadows which would be casted. | |||
I did some research today and found this useful diagram: deX76.jpg So what I understood from this is: First, I need to have a light source smaller than my object to minimise “partial shadows” (I would guess this is why a Camera Obscura also functions with a small light hole) Second, I need to find the right distance between the slime mold and the light source in order to get a shadow size in accordance with the room size. | |||
While researching I also stumbled upon this website: http://paulbourke.net/dome/mirrorbox/. It has really useful information about room projections. | |||
