You can make animations in 3d using the draw package:
(%i14) load(draw)$
(%i15) tay(n, x, y) := block(
[ts : taylor(exp(-x__^2-y__^2), [x__, y__], [0,0], n)],
subst([x__=x, y__=y], ts)
)$
(%i16) with_slider_draw3d(
n, 1+2*makelist(i,i,0,6),
color = blue,
explicit(exp(-x^2-y^2), x, -1, 1, y, -1, 1),
color = red,
explicit('(tay(n,x,y)), x, -1, 1, y, -1, 1),
zrange=[0,1]
);
