Glitch, A Browser-Based Massively Multiplayer Game

The trailer for the alpha release of Glitch, a browser-based, massively multiplayer game coming out in Spring 2011.

Glitch is a web-based massively-mutliplayer game which takes place inside the minds of eleven peculiarly imaginative Giants. You choose how to grow and shape the world: building and developing, learning new skills, collaborating or competing with everyone else in one enormous, ever-changing, persistent world.

NY Times has more on Glitch and Stewart Butterfield, founder of Tiny Speck which is developing the game.
