I'm having a bit too much fun with this...

import matplotlib.pyplot as plt
import numpy as np

def main():
    t = np.linspace(0, 4*np.pi, 1000)
    fig, ax = plt.subplots()
    ax.plot(t, np.cos(t))
    ax.plot(t, np.sin(t))

    inception(inception(inception(fig)))

    plt.show()

def fig2rgb_array(fig):
    fig.canvas.draw()
    buf = fig.canvas.tostring_rgb()
    ncols, nrows = fig.canvas.get_width_height()
    return np.fromstring(buf, dtype=np.uint8).reshape(nrows, ncols, 3)

def inception(fig):
    data = fig2rgb_array(fig)
    fig.clf()
    fig.add_subplot(111).imshow(data)
    return fig

main()
