Alice is a free "3D interactive graphics programming environment" developed at Carnegie Mellon University. The Windows-based authoring tool includes a program from a professor at the University of Tokyo that allows the user to create 3D models. Alice is then used to paint the objects, which can be included in Web sites and viewed by anyone with the free browser plug-in. The tools are known for their ease of use, but this does not limit the amount of documentation included on the Alice home page. Due to the extensive functionality of the programs, they are quite large and can take several hours to download on a slow connection.
