The default visual circuits in our brains may have evolved to optimally handle fractal patterns and textures. Straight lines, geometrical figures and featureles

The default visual circuits in our brains may have evolved to optimally handle fractal patterns and textures. Straight lines, geometrical figures and featureless surfaces may require activation of less optimal circuits. Anecdotally, I find being in environments made of featureless geometrical figures uncomfortable to be in.
