-“Time is a gradient and we use timepieces to slice that gradient into meaningful increments”
The name refers to the UTC -8 time zone of the West Coast of the USA.
The process of anodizing aluminum and metal-finishing inspired Krieger to produce these incredibly eye catching pieces of art . The gradient effect of each 8 layers of MINUS 8 is created by layering gradually more intensely-colored discs of anodized metal, the anodizing process is also a reference to time as the color intensity as a direct relationship with the time you spend anodizing it.
Another process PVD has been explored to create the grey version :
"Further research showed that Physical Vapor Deposition (PVD) was another industrial coating process with inherent time dependencies. A raw stainless piece is placed in a vacuum chamber where a hard coating accumulates over time. More time in the chamber produces a thicker coating and a more opaque color."
Apparently he's working on making prototypes right now, stay tuned.
