We worked closely with Bose to build an iOS companion app for the BOSEbuild Speaker Cube. The Speaker Cube is sold as disassembled hardware which young children, guided by the app, assemble themselves. In the app, we included interactive, instructional videos featuring Bose employees, who explain both how to assemble the Speaker Cube and how electricity is turned into sound. We also included complex animations that demonstrate certain steps in the assembly process. In July, 2016, Bose released the Speaker Cube and accompanying Sound app to great acclaim.
