Aurora Vesicles is a Public Art project for the city of Aurora Colorado at one of their new Light Rail Stations. The project begins with the crystalline formations of Igneous Lava Rock, the porous structure of which is generated through a process of tremendous heat and relatively rapid cooling, generating distinct and spectacular shapes. The patterns found in the structure of these rocks inspires the modular system from which the design is derived, excavated from within a lattice of sphere packing that allows for the repetition of regular segments. The material for the project is large volume re-purposed propane tanks, sectioned and jumbled together to create discreet modular segments that nevertheless form a contiguous surface with adjacent segments. Finally the surface of the carbon steel is finished with a copper plating and allowed to oxidize creating a spectacular natural patina that also seals and protects the sculpture.
