I was able to get things working okay in my development version of sage,
the sage git repo at ~/sage , but when i try to do this:
sage: t = Tachyon()
sage: t.show()
in my system non development sage installation, i get the same error as
before? Im using sage 6.3. Im assuming my installations di
No that's correct. The difference is that my way imports the *function* as
oppose to the *module* given by John. This is a python thing, see

Ok i did:
from sage.misc.viewer import png_viewer
at the top of the file tachyon.py, and then in my code as you suggest, in
Tachyon.show, i changed it from:
os.system('%s %s 2>/dev/null 1>/dev/null &'%(sage.misc.viewer.png_viewer(),
filename))
to:
os.system('%s %s 2>/dev/null 1>/dev/null &'%

Interestingly, i tried doing:
from sage.misc.viewer import png_viewer
first, but got the same error. But then i tried:
import sage.misc.viewer
and Tachyon.show works just fine now... So not sure what happened there.
