Description

Plotting with Pen. After Flake - "The Computational Beauty of Nature".

Class Methods

.new

Arguments:

drawFunc	A Function that draws something.
matrices	An array of arrays defining affine transformations. The inner array should have 6 values. See Pen's Pen: *matrix method. The outer array can be any length.
n	Number of iterations (depth).

Instance Methods

.makeWindow

Creates a Window and draws. Mainly for testing.

Arguments:

bounds	a Rect that define window size and position
background	a Color
