We're thinking it's not a coincidence that VentureBeat's Dean Takahashi chose Earth Day to publish an interview with Henk Rogers about his efforts to save the environment. You may remember Rogers as the visionary who first noticed an unassuming game called Tetris at a trade show and went on a crusade to get the game licensed outside of Russia. If you're not familiar with his story, we must insist you track down a copy of David Sheff's excellent book Game Over and read all about it. Go ahead ... we'll wait.

Done reading? Well, then you might be interested to know that Rogers is now using the money he made selling the Tetris license to do nothing less than getting the world completely off of carbon-based energy. After accomplishing that modest goal, Rogers says he hopes to realize the vision of his company's upcoming Blue Mars MMO by actually terraforming part of the red planet. Say what you will, you have to admit, the guy's ambitious.
