 When I first found out Sage (a year or two ago), it blew my mind. I'm 
still telling everyone about it ^_^

I've been learning slowly. Recently I've found the cell server. It's ideal 
for sharing my stuff with my friends, without nagging them to sign up at 
cloud or sagenb.

 I can't find this display_image thing anywhere in the Sage source, and 
 perhaps this is a Sage cell specific thing so that Tachyon things work in 
 that context (it's neither the command line nor the notebook server, so 
 some custom code may be necessary).  I'm not sure where you found the 
 display_image, though; even in the Sage cell patches to Sage [1] ... 


Following the track trace, I typed in the following in the cell and press 
tab:
sage.plot.plot3d.tachyon??

Then I checked the show() method...
def show(self, verbose=0, extra_opts=''):
# ... ommitted ...
if *sage.misc.display.is_registered('image'):*
filename = graphics_filename()
 self.save(filename, verbose=verbose, extra_opts=extra_opts)
sage.misc.misc.display_image(filename)
return


... and I found that  *sage.misc.display.is_registered()* curious. Then I 
also used tab for...
 sage.misc.display.

... and there I found the function display_image(). Then I guessed that sage
.misc.misc.display_image(filename)
had mistaken the second misc . From there I figured out the mentioned 
workaround.

Thanks for the advice! I'll be visiting [2] soon.

 Same code works fine at www.sagenb.org: it shows the three spheres

 I've searched sage-support, ask sage and trac sage, but couldn't find any 
 similar issue.

 Checking the source code I coded the following workaround within the cell (
 permalinkhttp://aleph.sagemath.org/?z=eJylkcluxCAMhu-V-g7cQiQLkaWHHniL3iOXcRKkLAhINXn7Go1QuhxHHMD-7c_YTsKID7TzuW_yHiiaXms4y0NYXCngYGlLFIxsQYOu69eXpBY3zUnKHjpoaxBatSBkA3weeqJ7OgLJKrUVCFw_HTOMVg2ImxvHIxIb7yCiJ3ssGNh6A7F7tC6dplG5-L7sXLS5il7Q7kmo5p_-g_ZPQ3VpP_qZmJldHK3LhPI0futZ_al31d_8TLj0PuujW2jj1fDyIk6kVhct97H6PWA4hyyrKaCfnY1DCZYPMH6RLC72XPk3F_2CZ7kHt7J0hX4DouKkKQ==lang=sage
 ):

 # t is as above
 # t.show() replaced by:
 filename = sage.misc.temporary_file.graphics_filename()
 t.save(filename)
 sage.misc.display.display_image(filename)

 Is this a bug in the method show() from the Tachyon class?
