As of this writing 'projection mapping' is one of the fastest growing mediums, being used in a variety of artistic and commercial projects. The basic idea: take a projector, point it at a physical volume like an object or an architectural element, and then map an image onto it.
The MadMapper provides a simple and easy tool for mapping projections. It removes a lot of the confusion related to this medium, effectively demystifying the process, allowing you, the artist or designer to focus on creating your content, and making the experience of mapping textures to physical objects in real time, fun.
MadMapper is built around the idea of sharing video content between applications.
