A peripheral device that is used with a mixed reality system that is thrown by the user of the mixed reality system and captures scene and mapping data of the area the peripheral is thrown into. Upon capturing the scene and mapping data, the peripheral transmits the data (in some embodiments, including processed results of evaluation of the data) to the mixed reality system. The mixed reality system displays a visual representation of the scene and mapping data on a near eye display. In some embodiments, the visual representation appears in real space enabling an effect where the user of the mixed reality system can see through walls or other obstructions. In some embodiments, the peripheral is configured to detonate upon the satisfaction of a variable set of conditions.
