Fractals: An Eclectic Survey, Part-1 [pdf]

Another eclectic fractal not listed here is the novel Infinite Jest. David Foster Wallace specifically noted the plot structure as a Sierpinski Gasket. You could think of the tennis academy, the halfway house, and the international assassins plots as the three subcomponent triangles within the overall triangle of the novel.

Of course literature doesn't fit cleanly - IJ simultaneously has a cyclical plot structure, but fractals are interesting way of thinking about the aesthetics of the book.

Another eclectic fractal is this impossible 3D triangular one which seems somehow connected to sheaf cohomology.
