Mazda developed a prototype wankel, rotary vehicle, that ran on hydrogen instead of traditional hydrocarbon fuels. The exhibit developed with Space Center of Houston needed a set of graphics that would explain how a rotary engine worked as well as illustrated some of the key benefits of hydrogen vehicles, mainly zero carbon emmisions. The signage Stimulacra developed highlighted many of the key points of the exhibit as well as get visitors excited about this new potential source of energy.
