Squeak is a programming system that is offered under an open source license, which makes it free to download. The website describes Squeak as "an open, highly-portable Smalltalk-80 implementation whose virtual machine is written entirely in Smalltalk, making it easy to debug, analyze, and change." The programming system can be used to create images, graphics, sound, games and websites. For example, the drawing function includes the ability to scale and rotate bitmap images at any color depth, anti-aliased TrueType fonts and vector graphics. The Documentation section includes several tutorials, bulletin board forums, and other online resources such as articles and books. In addition, a related SqueakLand.org website provides newly redesigned educational projects for students, parents, and teachers.
