Alice is a project formerly overseen by "Last Lecture" star, Randy Pausch and supported by Carnegie Mellon Univ. It is described as:
Alice is an innovative 3D programming environment that makes it easy to create an animation for telling a story, playing an interactive game, or a video to share on the web. Alice is a teaching tool for introductory computing. It uses 3D graphics and a drag-and-drop interface to facilitate a more engaging, less frustrating first programming experience.
Version 2 is freely available now. Version 3 is currently in development with underwriting by EA to "Revolutionize and Reinvigorate Computer Science Education in the US" with characters from
The Sims.
It is billed as a captivating new way to teach programming and worth a look:
