Ubuntu's Circle of Life
The red, orange and yellow circle logo of Ubuntu, a free Linux OS designed for consumers, looks like something you would toss to a drowning man, but if you glimpse a little closer you'll see three people forming a circle holding hands.
Group hug, anyone? This symbol of unity ties to the origin of the word "Ubuntu," an African expression that describes human solidarity and compassion.
The logo most likely to: be mistaken for a crop circle.
