I once wrote a program in BASIC (on my C64) which would make such a display (it's straightforward). I lost that program, but recreated a lookalike in Python:

I just spent way too much time making a matplotlib one. Example output: http://imgur.com/PtkkESv

  import pylab
  import scipy
  
  def gaussian(x, centre, xscale, height):
    return height * scipy.exp(-(2.*xscale*(x-centre))**2)
  
  def triangle(x, centre, xscale, height):
    y = height * (1. - scipy.absolute(xscale*(x-centre)))
    return (y>0) * y
  
  x = scipy.linspace(0., 1., 1501)
  shape = triangle#gaussian#
  
  def generate_noise(x, num_bumps, centre_min, centre_max, xscale_min,
                     xscale_max, height_min, height_max, shape=shape):
    y = scipy.zeros_like(x)
    for i in xrange(num_bumps):
      centre = centre_min + (centre_max-centre_min)*scipy.rand()
      xscale = xscale_min + (xscale_max-xscale_min)*scipy.rand()
      height = height_min + (height_max-height_min)*scipy.rand()
      print centre, xscale, height
      y += shape(x, centre, xscale, height)
    return y
  
  def generate_line(x):
    y = scipy.zeros_like(x)
    y += generate_noise(x, 100, 0., 1., 0., 300., 0., .003)
    y += generate_noise(x, 10, .25, .75, 20., 30., 0., .03)
    y += generate_noise(x, 10, .29, .45, 20., 30., 0., .03)
    return y
  
  num_lines = 85
  line_gap = .015
  for i in xrange(num_lines):
    base_line = (num_lines-i)*line_gap
    y = base_line + generate_line(x)
    poly = pylab.Polygon([(x[0], base_line)]+zip(x, y)+[(x[-1], base_line)],
                         facecolor='k', edgecolor='none', zorder=i)
    pylab.gca().add_patch(poly)
    pylab.plot(x, y, 'w', linewidth=2, zorder=i+.5)
  pylab.gcf().patch.set_facecolor('black')
  pylab.gca().set_axis_bgcolor('k')
  pylab.axis('equal')
  pylab.gcf().set_size_inches(8., 8.)
  pylab.savefig('pulsar.png', facecolor=pylab.gcf().get_facecolor(),

Whoah, that's a nice one. I wonder whether the original Arecibo data-set of the pulsar is still around somewhere. I tried to find it, but I didn't succeed.
