Sugarizer is a web version of the Sugar Learning Platform, and a branch of the main open source project, which is Sugar Labs.
They create educational games and apps, and its targeted audience are children ages 6-12 years old and educators.
I was introduced to Sugarizer when I joined the annual Google-Code In, where teenagers get to have a chance to contribute
to an open source of their choice. I chose Sugar Labs, and worked on Sugarizer. Some of the things I contributed there are
fixing bugs, documenting, adding enhancements, and submiting the web app Constellation Activity.
