有啊，不过很难用几何画板完成：
Slope_Apollonian {
; Ron Barnett April 23, 2005
; Implements the mapping algorithm of Susan Chambless
; Implements fBm in the global section using a noise array
; and modification of Damien's fBm code
; Circle perturbations added August 13, 2005
; improved duplicate removal code, November 18, 2005
