Origami is a file-sharing system you can talk with by email and text message. It promotes ad hoc learning spaces using a visual tag for linking physical spaces with existing collaborative software such as wikis, social bookmarking, and groupware systems. The Origami tag is designed for readability and can be hand-drawn or converted into sign language, Braille, or a short URL. Origami allows students to trade learning resources quickly and easily without interrupting conversation, lectures, or meetings.
