I think the true gridofgrids functunality is already implemented. Here's a replication of your Mathematica plots:  import numpy as np import matplotlib.pyplot as plt import matplotlib.gridspec as gridspec from itertools import product def squiggle_xy(a, b, c, d, i=np.linspace(0.0, 2*np.pi, 200)): return np.sin(i*a)*np.cos(i*b), np.sin(i*c)*np.cos(i*d) f = plt.figure(figsize=(8, 8)) # gridspec inside gridspec outer_grid = gridspec.GridSpec(4, 4, wspace=0.0, hspace=0.0) for i in xrange(16): inner_grid = gridspec.GridSpecFromSubplotSpec(3, 3, subplot_spec=outer_grid[i], wspace=0.0, hspace=0.0) a, b = int(i/4)+1,i%4+1 for j, (c, d) in enumerate(product(range(1, 4), repeat=2)): ax = plt.Subplot(f, inner_grid[j]) ax.plot(*squiggle_xy(a, b, c, d)) ax.set_xticks([]) ax.set_yticks([]) f.add_subplot(ax) all_axes = f.get_axes() #show only the outside spines for ax in all_axes: for sp in ax.spines.values(): sp.set_visible(False) if ax.is_first_row(): ax.spines['top'].set_visible(True) if ax.is_last_row(): ax.spines['bottom'].set_visible(True) if ax.is_first_col(): ax.spines['left'].set_visible(True) if ax.is_last_col(): ax.spines['right'].set_visible(True) plt.show()  It's a matter of taste, but I think you can get away hiding all spines, and just setting the hspace and wspace for the outer_grid to some small value (this is what I meant by 'adjusting the spacing'). I'll send a patch to the devel list shortly adding this example with the following documentation A Complex Nested GridSpec using SubplotSpec =========================================== Here's a more sophisticated example of nested gridspect where we put a box around outer 4x4 grid, by hiding appropriate spines in each of the inner 3x3 grids. it'll be placed on the gridspec page, after this section: http://matplotlib.sourceforge.net/users/gridspec.html#gridspecusingsubplotspec best,  Paul Ivanov 314 address only used for lists, offlist direct email at: http://pirsquared.org  GPG/PGP key id: 0x0F3E28F7
