Chalktalk is a graphic blackboard to teach sciences, computer sciences and more. A list of +250 objects ("glyphs") with specific behaviors is available. Glyphs can be connected and affect each others via an input/output maner, so meaningful mecanisms can be build. Glyphs can also be reprogrammed, stylized.
As a member of Future Reality Lab, I work with the team to bring this magical tool into VR.
