Brian W pointed me towards some more alternative icons for Mail.app.
They feature images of “Marianne” (Wikipedia 
), the national emblem of France and the embodiment of liberty and reason.
Brian likes them he says because “Mail.app is easier to hit in the dock when it isn’t the same blue color as every other Apple application!”
French site Cocoricones provides two sets of these Marianne stamps, each in blue, yellow, red, green and purple, one set in a traditional style and one with a more avant garde flavour (naturellement!).
Changing the icon itself is easy.
I’ve added the collection to the list of alternative stamp icons for Mail.app, making a total now of 295.
Love the new icons, but I don’t see a link to the set. Am I missing something?
Nevermind, I see it at the top of the list that you linked to. Doh!
No, you’re not missing anything. I am…. a brain. I’ve added a more helpful link now.
These are really great – the first icon replacement set I consider using long-term :-) (of course, I’m french, so I’m biased)
