I have previously posted about this (here). However, FlavorPill recently did a post on James Turrell and some of the images they had of Roden Crater and the installations, aka skyspaces that he is creating are just beautiful.
Also, every time I encounter the idea of Roden Crater and the largness of the project. Literally making a crater into a piece of constructed art. It just blows my mind.
