  VG.ClearAll(255, 255, 255);
  Randomize;

  // Draw 100 random lines 
  for i := 1 to 100 do begin
    VG.LineColor(random(255), random(255), random(255), random(255));

    VG.LineWidth(random(100) / 10);

    VG.Line(random(ClientWidth - 20) + 10.5, random(ClientHeight - 20) + 10.5, 
     random(ClientWidth - 20) + 10.5, random(ClientHeight - 20) + 10.5);
