Logo Design

I'm currently in search for a logo for a new project I'm launching called Repurposed Labs, giving a new purpose to old computers. During this process, I've also come to realize the brilliance behind a well designed logo. I've always loved the simple yet meaningful design of FrontlineSMS, HopePhones, MobileActive, Ubuntu, SiGeneration and SwiftRiver.

FrontlineSMS, is open source software that uses SMS to empower it's users. Their logo is a speech bubble out of the word SMS, with ascii characters \0/ inside which represents raising your arms up in victory. The brilliance behind the logo is apparent in the sister projects, FrontlineSMS:Medic \+/, FrontlineSMS:Credit \$/, FrontlineSMS:Legal \=/, FrontlineSMS:Learn \?/ and FrontlineSMS:Radio \~/ which reuse the logo but change the message inside.

HopePhones, is an initiative to collect used cell phones so they can be repurposed by community healthcare workers in developing countries. Each old phone donated can help save a life in a developing country, thus the angel wings on the phone in their logo.

MobileActive, is a global network of people using mobile technology for social impact. Their new logo is pretty ingenius, could be interpreted as four people raising their arms in protest or four mobile devices with antennas.

Ubuntu, is an open source community that provides a free and easy-to-use operating system for the world. The word 'ubuntu' is a Southern African ethical ideology which means 'humanity towards others'. Their logo could be interpreted as six components fitting together or three people of different color united.

Social Innovation Generation (SiG) is a centre in Toronto whose goal is to use technology to solve serious social problems. Their logo looks like a dandelion flower with the seeds blowing in the wind, which matches their mission to help seed innovation.

SwiftRiver is an open source platform that helps users add context to realtime data. Their logo is one of my favorites; it naturally has a river shape, a visible letter 'S', as well as the thumbs up and thumbs down which is key functionality to the platform.

So what are your favorite logos? How do their design capture the organization's mission?
