In the book Introduction to Maple by Andre Heck books.google.co.uk/books  the author manage to plot the canadian flag
in maple by using the following code:
 

restart:
with(plots):
with(plottools):

X := proc (cc) local S, R, mapleleaf, rectangles, border:

S := proc (t) options operator, arrow; 100/(100+(t-(1/2)*Pi)^8) end proc:
R := proc (t) options operator, arrow; S(t)*(2-sin(7*t)-(1/2)*cos(30*t)) end proc:
mapleleaf := plot([R, proc (t) options operator, arrow; t end proc, -(1/2)*Pi .. (3/2)*Pi], coords = polar, axes = none, color = cc, numpoints = 1000):
mapleleaf := subs(CURVES = POLYGONS, mapleleaf):
rectangles := rectangle([-5, -1], [-3, 4], color = cc), rectangle([3, -1], [5, 4], color = cc); border := plot({-1, 4}, -3 .. 3, color = black):

display([mapleleaf, rectangles, border], view = [-5 .. 5, -1 .. 4]) ;

end proc:

Ap := Array(1 .. 2, 1 .. 2):   

Ap[1, 1] := X(red):         Ap[1, 2] := X(blue):    
Ap[2, 1] := X("green"):    Ap[2, 2] := X("Orchid"):

display(Ap);
