One of LinkedIn's designers, Ashley Hall, was kind enough to come up with this logo proposal. I like it quite a lot. It goes with the idea of Giraph and networks, creating the icon of the giraffe from a stylized network, with the eye being a particularly active node.
We have vector versions of both the regular and reversed versions. It's designed to work well both at large and small sizes. This is quite helpful for using the logo in all different types of situations; the website, presentations, tshirts, etc.
I'm planning on using this for my Berlin presentation and would like to get agreement on standardizing on it for the project. I'm +1.
