The logo

The Trace Institute Logo

The Trace Institute Logo is a working demonstration of the mathematical theory. The mark references square matrices, the fundamental objects of linear algebra, quantum theory, and Markov networks. It contains a fractal self-similarity that mirrors the structure of the Recursive Trace Logic.

The logo also embeds a real perceptual illusion. The geometry produces a visual effect that your visual system resolves in a specific way, even though the marks on the page are neutral to that interpretation. This is an example of the Interface Theory of Perception: what you perceive is not what is there but instead what your perceptual system constructs.

The logo is the thesis, while the illusion is the argument.
