Fantastic Contraption is a puzzle game in which players use the motion controls to construct machines from building materials in order to meet challenges.

The developers helped lead a lot of the early thinking around UX and design in modern VR, including how to capture traditional UI elements, such as menus, saving and loading games, sharing content, et cetera, when a flat-screen menu is not an option.
