Sure:

blob {
        threshold 1
#declare curX = -15;
#declare curZ = -15;

#while (curZ < 15)
        sphere {
          <curX, 0, curZ>, 0.49, 1
        }
        #declare curX = curX + 0.5;
        #if (curX > 15)
                #declare curX = -15;
                #declare curZ = curZ + 0.5;
        #end
#end


        texture {
                pigment {
                        color rgb <1,1,1>
                }
                finish{
                        diffuse 0.3
                        ambient 0.0
                        specular 0.6
                        reflection {
                                0.7
                                metallic
                        }
                }
        }
}
