What Is an Activity?
Sugar applications are called "Activities". Activities include an application as well as sharing and collaboration capabilities, a built-in interface to the Journal, and other features such as the clipboard.
The Journal Activity is pre-installed. Other Activities can be distributed as part of an Activity Pack. There are many, many others you can install yourself.
Activities you have specified as favorites appear as a ring of icons around the XO icon in the center of the Home View. All the Activities you have installed are shown in the List mode of the Home View.
Some Activities allow Sugar users to work and learn cooperatively. For example, Write allows several users to collaboratively create a document. Read allows several users to read the same document or a teacher to share a book with an entire classroom. Memorize allows a group of users to play a game together.
Another class of Activities allow users to write software. A variety of computer languages such as Logo, SmallTalk, CSound, and Python are supported within the TurtleArt, Etoys, TamTam, and Pippy Activities.
