Ryan Sipes, on The Thunderbird Blog:
[…] After nearly 20 years, we are thrilled to share a completely redesigned Thunderbird logo that honors our history and vital connection to Mozilla, while carrying us forward into the next 20 years.
Great looking logo and application icons. That’s not something you see all the time. Of course, no surprise:
But you should never forget your roots, which is why we asked Jon Hicks, the creator of the original Firefox and Thunderbird logos, to re-imagine his iconic design in light of Thunderbird’s exciting future.
I’m a fan of his work, so completely biased. He had some nice comments on mastodon about the logo.
