Programming for the under-tens

You might think you're pretty hot stuff because you've figured out how to change your Facebook status from your iPhone, but you've got nothing on nine-year-old Lim Ding Wen.

This young prodigy from Singapore is fluent in six programming languages, according to a BBC report this week, and his newest creation, an iPhone drawing game called Doodle Kids, has racked up over 4,000 downloads in just two weeks. He wrote it for his younger sisters, who love to draw.

Doodle Kids, which lets players sketch with their fingers on the iPhone's screen and shake it, Etch-A-Sketch-style, to clear, has already racked up a healthy three-and-a-half star rating on the App Store. One reviewer commented: "Awesome app!...Amazing that something like this was made by a 9 year old".
