KidPad is a collaborative storytelling tool for children, designed by children and academic researchers. KidPad provides drawing, typing and hyperlinking capabilities in a large two-dimensional zoomable space. Through these capabilities, children can create stories by drawing story scenes and linking them together in two-dimensional space. KidPad supports multiple users through the use of multiple mice. Elementary schools in England and Sweden have made KidPad a part of their curriculum since 1998.
