In a short text written for Site, Enns describes the project as a proposal for a 12-meter-tall solar clock, a monolithic sandstone pillar whose sculpted form would combine ancient methods of timekeeping with digital fabrication.
“The resulting parametric script,” Enns writes, “which begins with the hourly solar location data and subtracts a channel of sandstone from the column for each hour, produces a complex Swiss cheese of voids that are unique to the latitude, longitude, and elevation of the design site.”
It would be incredibly interesting to see this approach applied to blocks of sandstone of varying heights, depths, and dimensions, producing what I imagine might be complex, vertebral stacks of perforation and shadow, alternately as broad and imposing as medieval watch towers or as diminutive and fragile as flutes of ornament hidden on the corners of existing buildings.
As the chronographic marks surrounding the pillar also seem to indicate, the graphic possibilities for telling time with this are presumably endless—colors, patterns, arcs, loops, textures, materials.
For now, the newest issue of Site is not online, but click through to Enns’s own portfolio for a bit more.
