The Sierpinski triangle is literally showing off here! While someone's dreaming of a base-3 fractal face transformation, this mathematical showboat is like "I've been doing that since 1915!" The Sierpinski triangle has a fractal dimension of approximately 1.585, making it neither a 1D line nor a 2D shape, but something delightfully in-between. It's formed by repeatedly removing the middle triangle from an equilateral triangle, creating an infinite pattern of self-similarity that would make any face look mathematically fabulous. The surrealist painting just adds that extra layer of mathematical existential dread.
