Alice

"Alice (www.alice.org/) is a revolutionary programming tool that enables computer novices to create computer animations using a drag-and-drop interface. Now used by 10 percent of U.S. colleges and universities and also in many high schools, Alice makes computer science more accessible to students by eliminating the initial frustrations associated with learning how to program computers. A version of Alice developed by Caitlin Kelleher, Pausch’s final Ph.D. student, enhances Alice’s storytelling capabilities and has been developed for use in middle schools, particularly by girls.

Carnegie Mellon makes Alice available free as a teaching tool." -- Webwire
