I wouldn't call it pussying out, i spent most of my free time yesterday afternoon working on icons, it wasn't like i was trying to do something quick and easy.

I'd like to think that at least one of the sets i did yesterday (preferably set2) will be given the time of day and not just dismissed for something more flashy and animated, not just because otherwise it will have been a waste of my time but i think we already have a suitable one to use.
Just seems a bit off as well that we're going to lengths to come up with something that's animated when we have a perfectly good static set ready to use, or at least try.
I may still have a go this weekend at doing an animated set like the one i posted above, i won't write that off. To note though all the animations posted so far will freeze and look like either

or

for anyone that has them disabled. Neither of them are as clear as

of set2. If the first 2 were already easy to spot for everyone we wouldn't still be doing this i don't think.
It's going to come down to opinion at the end of the day like animated avatars would, but putting aside my comments in the other post i don't honestly think the set needs to be animated to look good and do it's job either, as set2 has shown (at least to me as i still prefer the latter).
