Award-winning author Neal Stephenson kills his $500,000 Kickstarter swordfighting game, Clang

Kickstarter is a risky business, and another high-profile project on the crowdfunding site is now officially dead.

In a lengthy Kickstarter update post, science-fiction author Neal Stephenson explained that his historically realistic motion-controlled swordfighting game, Clang, is no more. This is despite raising over half a million dollars from more than 9,000 backers, many of whom are now pretty angry.
