the last week's discussion about Echo was pretty fruitful I think and
showed that the general opinion is to not include Echo in F10 as a
default icon set. I take this as an opportunity to rethink the general
goals of echo and "give some credit" to various critics.
The main reason why *I* think not to have Echo in F10 as default is
incomplete coverage of other-than-48x48-px sizes and shortcomings of the
scalable icons that are supposed to fill the gap. We're slowly but
steadily improving that and I think Echo should not be submitted for
inclusion in Fedora as default icon set before this issue is resolved.
Next there is a general coverage where we are already close to gnome
upstream icon set. We will be improving that as well. I'd like to focus
on (nearly) full coverage of Desktop Live Spin, KDE Live Spin and XFCE
Live Spin (others as well, but I don't have them all in memory). So if
you are missing echo styled icons in your favourite application that is
included in one of those spins, feel free to file a bug . It will not
be handled instantly, but it helps us deciding what icons need to be
That also pretty much summarize our main goal, which is similar to what
tango project has, to cover various desktops with one icon set.
Finally I'd like to throw some fuel for discussion (mainly on the
art-list). We are a lot criticized for inconsistencies in the projection
we use in echo. Strictly speaking we are using 3 different types of
projections and we have rules which is used where and we are pretty much
consistent with that. Especially we do not introduce any other different
projections to these and thus trying to keep the set consistent. In that
we are even better than gnome - I discovered a few of icons there that
does not adhere to their projection guidelines and have their own
(though usually only slightly different from the main types).
But on the other side it turns out that having three main types of
projections is too much for an icon set and that having two is about the
right number. So I started discovering the idea a bit more  with the
hope to come to some conclusions (in the future) about echo projection
guidelines. I am thinking about creating a parallel icon set that would
use echo guidelines sans the projection ones, but I have not yet decided
on the used type of projections.
My top candidate currently is perspective projection from a similar
viewpoint as used by gnome icon theme - that would much improve our
coexistence with it. I am attaching proof of concept icon sketches
following this projection rule. I plan to explore other types of
projections as well and write another blog post (a follow-up to )
later (but it will take some time, since I don't have much spare time
available for echo lately).
