Be nice to your little brother: he could be the mastermind behind your next cool iPhone application.
Lim Ding Wen, 9, is the creator of 'Doodle Kids,' an iPhone application that allows children to use their fingers to draw on the screen, Fox News reported today.
The 'Doodle Kids' application has been downloaded more than 4,000 times from the Apple Web site in the past two weeks. Users simply trace their fingers across the iPhone to create their artwork, then shake the screen to erase when finished.
"I wrote the program for my sisters, who like to draw," said the fourth-grader, whose siblings are 3 and 5 years old.
The Singapore-born Lim is fluent in six programming languages and started using the computer at the age of two, according to Fox News. He has since written more than 20 programs.
Lim's father, Lim Thye Chean, works at a local technology firm and also writes iPhone applications.
"Every evening we check the statistics e-mailed to us to see who has more downloads," he said.
Lim, who likes reading science fiction books, said he is in the middle of creating another iPhone app, a game called "Invader Wars."
