#1895 — Re: Mathematica loop question

Also cool:

Module[{num = 10, m = RotationMatrix[3/4 Pi], yMax},
  yMax = Last[m.{num, 1}];
  Graphics[{Table[{x, y} =
      m.{i, j}; {EdgeForm@{Thick,
        ColorData["TemperatureMap"][1 - y/yMax]},
      ColorData["TemperatureMap"][y/yMax], Disk[{x, y}, 0.4]}, {i, 0,
      num}, {j, 0, i}]}]]

or

Module[{num = 100, m = RotationMatrix[3/4 Pi], yMax},
  yMax = Last[m.{num, 1}];
  Graphics[{Table[{x, y} =
      m.{i, j}; {ColorData["TemperatureMap"][y/yMax],
      Disk[{x, y}, 1]}, {i, 0, num}, {j, 0, i}]}]]
