Butterfly effect: an augmented reality puzzle game

Butterfly effect is a 3D puzzle game using augmented reality. The key motivation was to create a game that leverages the structure of the physical world during gameplay without requiring the computer to have a detailed model of the space. The butterflies are virtual, but the space the player navigates is physical. The player travels her environment, collecting the butterflies. For butterflies that are out of reach, the player can rotate the virtual world in 90 degree chunks about an arbitrary axis to bring them to an accessible location.
