Gridpaste

Gridpaste is an online math tool to share computations, transformations, and annotations on geometric structures in a coordinate plane. One starts with a clean board and places their geometric elements and performs actions on these elements in a recordable sequence. The sequence may then be saved and shared by a unique URL to colleagues or instructors.
