In this series of sculptures and images, Tille makes the abstract signals of thought concrete. The process begins with EEG recordings of his own mind and that of others as their thoughts travel to the subjects they find personally relevant. Tille interrogates the electrical waves for the most interesting patterns and then converts them into a three-dimensional shape, forming the basis for Konkretion. Each work from Konkretion brings forth one or more thoughts, the contents of which remain mysterious. Captured in an undulating form, the brain waves are not precisely readable to us as viewers. They therefore become symbols of our agency, as well as the profound unknowability of others’ minds.
