Publicly, the man behind Ubuntu, Mark Shuttleworth comes across as a very reasonable chap. But don't let that fool you into believing Shuttleworth is just your average, run-of-the-mill nerd. This man may very well be the biggest bad boy of them all. I'll leave you with these facts so you can make up your mind for yourself.
1) He is the only man on this list who has traveled into space.
2) He is on a quest for world domination - pushing Ubuntu into every aspect of computing, including server, TV and mobile phones.
3) He is responsible for the "Unity" project, Ubuntu's new user interface.
He may not look much like Hugo Drax but, otherwise, there are an awful lot of parallels to Moonraker.
