I like watching TED Talk videos, including lots videos from TEDx. Recently, I stumbled across a video by Thomas Suarez from TEDxManhattanBeach event.

From the video description:

Thomas Suarez is a 6th grade student at a middle school in the South Bay. Tom been fascinated by computers and technology since before kindergarten. Recently, he’s been focused on the development of applications for the iPhone, and has established his own company, CarrotCorp. His most successful ap is one he terms “an anti-Justin-Bieber game” called “Bustin Jieber”. “It’s is a variation on the Whac-a-Mole theme,” he explains.

Not only he does a great work,  I think he’s very good at his presentation too :)
