recursive blues :(

Hi,

Why doesn't the following function represent a recurvive and periodic
function?

\!\(\*
  RowBox[{\(f[x_]\), " ", ":=", " ",
    RowBox[{"\[Piecewise]", GridBox[{
          {\(f[x + 2]\), \(x < \(-0.5\)\)},
          {"2", \(\(-0.5\) = \ x = 0.5\)},
          {"1", \(0.5 < x = 1.5\)},
          {\(f[x - 2]\), \(x > 1.5\)}
          }]}]}]\)


What are all possible ways to represent periodic functions?

Thanks,
Ash
