In response to illegal logging activity in California’s threatened redwood forests, the Center for Tactical Magic has designed the Criket Activated Defense System project (we’re talking about a project, not an actual installation) which establishes a system of deterrence through the technological augmentation of natural systems.
An electronic device receives distressed cricket chirps and translates the sound into a firing signal for anti-logger missiles. The device simply recombines consumer surveillance products (essentially “bugging” devices) with model rockets – both trickle-down goods from the military-industrial complex.
Crickets have evolved to transmit a very precise frequency should they feel threatened by the encroachment of an invasive species. The system is activated only when a significant number of the cricket population voice their consternation over a relatively broad area.
