Shorter than the Day
The New York-based artist captures the sky as it changes from cerulean blue morning to a colorful sunset to the many shades of night through nearly 1,000 photographs of the sky. Each printed image is fastened to the aluminum and steel with alligator clips and is revealed as viewers move around the massive work, just like the earth circles the sun to mark a day.

stellar axis aligns 99 blue spheres to stars in the antarctic sky
The Stellar Axis land art project is currently being deployed in Antarctica, to be completed for the Southern hemisphere Summer Solstice on 22 December 2006.
Perhaps the largest and most ambitious arts project to take place in Antarctica, Stellar Axis is the work of the internationally known, Los Angeles based artist, Lita Albuquerque, and is sponsored by the US National Science Foundation and US Antarctic Programme.
The concept is to mirror the southern constellations through the placement of 99 blue spheres on the Ross Ice Shelf in Antarctica.
