Twitter has changed its logo. The new logo looks cleaner. The “hair” on the old bird is gone. Replacing with a bird who seems to have more pride with its head looking up.
From Twitter blog:
Our new bird grows out of love for ornithology, design within creative constraints, and simple geometry. This bird is crafted purely from three sets of overlapping circles — similar to how your networks, interests and ideas connect and intersect with peers and friends. Whether soaring high above the earth to take in a broad view, or flocking with other birds to achieve a common purpose, a bird in flight is the ultimate representation of freedom, hope and limitless possibility.
Here is a video to introduce the new logo.
