```pic1 = Plot[8 Sin[Pi t] Exp[-t], {t, 0, 4}]

plot4[p_] :=
Module[{R, p1, p2, p3},
R[q_] := Show[q /. {x_?NumericQ, y_?NumericQ} :> {-y, x}];
p1 = R[p]; p2 = R[p1]; p3 = R[p2];
Show[{p, p1, p2, p3}, PlotRange -> All]];

plot4[pic1]

This (from some book) worked in Mathematica 4, but not now:

I can't figure out how to do it today.  Thanks for any suggestions.
