A decade in the making, 𝘊𝘦𝘯𝘵𝘶𝘳𝘪𝘦𝘴 𝘰𝘧 𝘵𝘩𝘦 𝘉𝘳𝘪𝘴𝘵𝘭𝘦𝘤𝘰𝘯𝘦 is a monumental artwork by artist and conceptual philosopher Jonathan Keats, commissioned by the Nevada Museum of Art in partnership with The Long Now Foundation. It is composed of two parts: a giant arboreal clock built by clockmakers Phil Abernethy and Brittany Nicole Cox, and a land art installation at Long Now's Nevada Bristlecone Preserve, home to the world's longest-living trees.

This video is also a sneak peek at 𝘌𝘭𝘥𝘦𝘳𝘴 𝘰𝘧 𝘛𝘪𝘮𝘦, a documentary short about the creation of 𝘊𝘦𝘯𝘵𝘶𝘳𝘪𝘦𝘴 𝘰𝘧 𝘵𝘩𝘦 𝘉𝘳𝘪𝘴𝘵𝘭𝘦𝘤𝘰𝘯𝘦, which is in festival selection throughout 02026. Follow Long Now for future screening dates and details.
