Pump Up The Volume [1990] - Pixies Wave Of Mutilation (UK Surf version) 1  The film is well worth a watch but somewhat dated - Both this scene and the Pixies song has stuck in my mind for a very long time. 2  My favorite scene in the film.
A fractal is a natural phenomenon or a mathematical set that exhibits a repeating pattern that displays at every scale. It is also known as expanding symmetry or evolving symmetry. If the replication is exactly the same at every scale, it is called a self-similar pattern.
We did experiment as to what methods and what parameters sounded the best, especially with the fractal motion method. Our findings were that music with a fractal dimension near 1.4 sounded the best (the fractal dimension is a measure of how close to white or brown noise the fractal is). The authors' personal favorite tunes are those generated by the single note L-Systems and the chord progression L-Systems.
