The Philosopher Cube is , conceptually, an alien cube that has landed beside Rideau Centre, a shopping mall in Ottawa, looking for answers to some typically philosophical questions in an attempt to better understand the human race. Using a combination of C++, OpenGL, and 3D projection mapping techniques an illusion of this strange cube floating in front of Rideau Centre at the corner of Nicholas and Daly avenue, and manipulating the wall behind it to form its questions, is created.
