Documentation of the installation "Der Gedankenprojektor" (The Thought Projector) by alien productions.
A professional-grade fundus camera as used by ophtalmologists provides high-resolution images of the visitor's retina, interior surface of the eye and iris. These images are then transferred to a projection screen set up in the middle of the installation space. A computer then evaluates the images produced and reveals the hidden thoughts that have manifested themselves on the visitor's retina.
The results are then projected onto the left wall as a "Thought Frieze". The images from the eye and the interior surface of the eye as well as the thoughts that have melded into them are then streamed onto the internet. Online users, for their part, can comment on or attempt to interprete the images, and this material, in turn, is streamed back to the installation and projected onto the right wall.
