Get a "Nicktropolis" Life

What is being touted as a kind of "Second Life for kids", Nickelodeon's "Nicktropolis" is a place where:

Children will be able to create their own personalized 3D rooms on the site, which launches on Tuesday, and move through Nicktropolis by taking on a self-designed 3D avatar similar to those on popular virtual world Second Life, choosing from an array of hairstyles, skin tones and clothing styles.

The site will feature gaming, online video, popular Nickelodeon brands and other elements to help children interact with each other or Nickelodeon characters in
real time.
