Leonardo's vision embraced more than meets the eye. His plants, his anatomy, his machines exuded potential for movement. Each was a wellspring of energy.

The Mechanical spring was a metallurgic innovation newly mastered in Leonardo's Renaissance. Leonardo foresaw its influence in clocks , crossbows and flintlocks, in wind-up cars and robots. If a device could have two states at once compressed and spring or stretched and recoiled, is it not emblematic of the universal energy that Leonardo's eye uncovered?

Consider the now familiar wire spring. Transform one, several or many to explore the infinite expressions the creative eye finds coiled in this simplest emblem of latent energy.
