The plan below uses the 99's Black Rock city design as a model and then "pentagonism" is applied.

The pentagon is the city boundary and this influenced the work. The spine of the city is made of 1st iteration {5/1}-star-polygonal fractal (red pentagons), then the 2nd iteration (blue pentagons) and finally the fifth iteration (black pentagons filled with yellow). The yellow pentagons (the smallest) are computed by computer, however everything else is fitted by hand and processed with Incscape.

Fractal coordinate system is applied and every pentagon has its unique number (except the Camp Center). The counting starts with 0 from the central pentagon, then rotates clockwise until it reaches its 6th element (non central fractal elements have 7 pentagons). For clarity, the Element 1 which is dummy is enumerated. It is divided by 7 pentagons, (1,0) (1,1) (1,2) (1,3) (1,4) (1,5) and (1,6) where (1,3) is also divided by (1,3,0) (1,3,1) (1,3,2) (1,3,3) (1,3,4) (1,3,5) and (1,3,6). The same logic could be applied for the enumeration of all the pentagons at any scale.

The Burning Man is placed at (0,0) pentagon and is drawn as the Vitruvian Man of Da Vincy reminding us that the golden ratio is all over the city plan. Indeed, the scaling factor of the pentagons is 1/phi squared. This is the self-similarity scaling rule of the city plan that connects the pentagonal boundary of the site with each individual pentagonal element of Black Rock. The Vitruvian Man is also reminding us that the golden ratio self-similarity continues all the way to the human proportions of the Black Rock citizens. Hence, the city is designed as a natural extension of its inhabitants.
