细看还是有差别，继续寻找。这下应该正确了：

终于弄出一个比较满意的来：

这个厉害的。

不，还是软件利害。

这样的效果也挺有趣：

漂亮！

改变着色方式：

不得不赞叹！第二幅图尤其精彩，榕兄阐明一下着色算法。

还不是很成熟，这种效果我很早以前就一直想效仿，但总不成功，之前常老师也研究过效果好象更好。它是UF中的一个着色特效，代码如下：
Triangle {
;
; Variation on the Triangle Inequality Average coloring method
; from Kerry Mitchell. The smoothing used here is based on the
; Smooth formula, which only works for z^n+c and derivates.
;
; Written by Damien M. Jones
;
init:
  float sum = 0.0
  float sum2 = 0.0
  float ac = cabs(#pixel)
  float il = 1/log(@power)
  float lp = log(log(@bailout)/2.0)
  float az2 = 0.0
  float lowbound = 0.0
  float f = 0.0
  BOOL first = true
loop:
  sum2 = sum
  IF (!first)
    az2 = cabs(#z - #pixel)
    lowbound = abs(az2 - ac)
    sum = sum + ((cabs(#z) - lowbound) / (az2+ac - lowbound))
  ELSE
    first = false
  ENDIF
final:
  sum = sum / (#numiter)
  sum2 = sum2 / (#numiter-1)
  f = il*lp - il*log(log(cabs(#z)))
  #index = sum2 + (sum-sum2) * (f+1)  
default:
  title = "Triangle Inequality Average"
  helpfile = "Uf*.chm"
  helptopic = "Html/coloring/standard/triangleinequalityaverage.html"
$IFDEF VER50
  rating = recommended
$ENDIF
  param power
    caption = "Exponent"
    default = 2.0
    hint = "This should be set to match the exponent of the \
            formula you are using. For Mandelbrot, this is usually 2."
  endparam
  param bailout
    caption = "Bailout"
    default = 1e20
    min = 1
$IFDEF VER40
    exponential = true
$ENDIF
    hint = "This should be set to match the bail-out value in \
            the Formula tab. Use a very high value for good results."
  endparam
}
下面是我根据这段代码做的结果，请梅老师看能否将它完善。

uf我可是外行。不懂的地方我到时请教。
