"Scratch deals well with 2-D graphics, text, and other somewhat "flat" programming concepts. By contrast, Alice teaches programming fundamentals in the form of 3-D movies and games. Alice is developed in Java, and is somewhat like Scratch in that you build things in a drag and drop interface.
"Alice, developed by a group of researchers at Carnegie Mellon University, has releases for Linux, Mac OS X, and Windows, and is released under an aptly titled Alice License. The environment is open source in the sense that you can download and examine the source code, but the creators prefer to work exclusively in-team, and don't take outside contributions. Alice has been around since 1999, making it one of the oldest and most developed environments for teaching children how to program. It is because of this that it's used in schools all over the world."
