Attached logo with transparent background (used GIMP for this).
Unfortunately I can't
make Inkscape compile on my system to see if this can be done automatically.

However that version only uses binary transparency, and it's the version
rendered
against a blue background, so it will still only look good against a blue
background.

http://code.google.com/p/sympy/issues/detail?id=1520
As you said, Mathematica does not match non-existent symbols.
In[1]:= x*y /. (2*x) - 2
Out[1]= x y
In[4]:= x*y /. 2 x - 2
Out[4]= x y
Neither does Maxima:
(%i4) subst(2,2*x,x*y);

Right, but still probably better if sphinx changes the color a bit (as
opposed to the
white background).

What about:

Not sure. IMHO it's just a such cosmetic issue - I wonder what Chinese

Hi,
while waiting for a cofee, I browsed an old Mathematica book from
1996, and let me assure you, we still have things to catch up on
almost every page. :) But this caught my attention, try it in sympy:
In [1]: e = ((2/(27+3*sqrt(69)))**(S(1)/3) +
((27+3*sqrt(69))/2)**(S(1)/3)/3)**3

It looks like Maple also has problems with the last few digits. I
guess you need to evaluate to several digits beyond what you want to
ensure that the ones you want are accurate:
a := ((2/(27+3*sqrt(69)))**(1/3) +((27+3*sqrt(69))/2)**(1/3)/
3)**3;
