Wired have a cool piece up pointing out the potential of modders who go for simple, rather than complex.

Using World of WarCraft's mod tools, a Uni student by the name of Michael Fromwiller, made his own version of the popular puzzle game Bejeweled (which he called Besharded) that seemed so fitting, Bejeweled publisher, PopCap, contacted him and offered him a job creating an official Bejeweled add-on for World of WarCraft.

Fromwiller said he created the original mod because it "could cure plenty of hours of boredom." Neat.
