代码如下：
MandelPaper {
; Ron Barnett, December 1998
; To use this as a tiler, use the aspect ratio transformation
; Set the aspect ratio to 1.0
; This is based on an old fractint tiler of Ray Girvan's
init:
   #z=(@fn1(@fn2(real(#pixel)))+flip(@fn1(@fn2(imag(#pixel)))))/@p2
loop:
   #z = #z*#z + @p3
bailout:
  (@test == 0 && |#z| <= @bailout) ||                                         \
  (@test == 1 && sqr(real(#z)) <= @bailout) ||                                \

  (@test == 6 && (sqr(real(#z) + imag(#z)) <= @bailout))

不错，几何画板的效果图比UF更好看。

我还是比较喜欢有小宝贝的REB004H：

柳老师的这组分形用于布料上，搞成碎花儿水印效果，一定很时尚。
