to promote tiger energy biscuits for kids, we built a playground that generates electrical energy when kids use it. for maximum impact, we installed it on the grounds of the oldest orphanage in the philippines.
the best technical university in the country helped us design a merry-go-round & a see-saw that channeled kinetic energy into a generator that produced electricity.
my team transported & assembled the equipment ourselves–four burly art directors & me–in thick post-deluge mud. worth it.
