It would be even nicer if we could get the image of a pencil in the
middle of the circle, to indicate docs.
I know, nobody uses a pencil any more, but it does signify writing, as
in many of the gnome png icons, like this one:
which is for gedit.
(Just a suggestion)
Basically the logos are nice,
but i think they should have
a closer relationship to the
Open MPI logo than simply rounded corners;
for instance the same colors (blue to black gradient)
or those nice curved lines.
