### 60.4 Definitions for Koch snowflakes

Function: snowmap (ent, nn)

  Koch snowflake sets. Function `snowmap` plots the snow Koch map over the vertex of an initial closed polygonal, in the complex plane. Here the orientation of the polygon is important. Argument nn is the number of recursive applications of Koch transformation; nn must be small (5 or 6).

  Examples:

      (%i1) load("fractals")$
      (%i2) plot2d([discrete,
                    snowmap([1,exp(%i*%pi*2/3),exp(-%i*%pi*2/3),1],4)])$
      (%i3) plot2d([discrete,
                    snowmap([1,exp(-%i*%pi*2/3),exp(%i*%pi*2/3),1],4)])$
      (%i4) plot2d([discrete, snowmap([0,1,1+%i,%i,0],4)])$
      (%i5) plot2d([discrete, snowmap([0,%i,1+%i,1,0],4)])$
