The appearance can change significantly by just varying the color scheme.

Partition[
  DensityPlot[
     Sin[129*Abs[(x + I y)^-1]],
     {x, -2.5, 2.5}, {y, -2.5, 2.5},
     PlotLabel -> #,
     PlotPoints -> 18,
     Mesh -> False,
     Frame -> False,
     ColorFunction -> #] & /@
   {Hue, "TemperatureMap",
    "NeonColors", "GreenPinkTones",
    Blend[{Red, Yellow}, #] &,
    Blend[{Red, Blue, Yellow}, #] &},
  3] // Grid

Or by changing the PlotPoints

Partition[
  DensityPlot[
     Sin[129*Abs[(x + I y)^-1]],
     {x, -2.5, 2.5}, {y, -2.5, 2.5},
     PlotLabel -> "PlotPoints -> " <> ToString[#],
     PlotPoints -> #,
     Mesh -> False,
     Frame -> False,
     ColorFunction -> Hue] & /@
   Range[4, 12], 3] // Grid
