Lux Aeterna, Latin for Eternal Light, is one of the most famous compositions of the 21st century. Originally composed by Clint Marshall, a fully orchestrated version was arranged for by Simone Benyacar, Daniel Nielsen, and Veigar Margeirsson for The Lord of the Rings - The Two Towers. This is the version that the artist, Roy Koganti, was most inspired by, and thus chose to craft a visual composition for.

Hoping to share with others the same sense of grandeur and emotion he felt from this song, the artist worked on two separate compositions that eventually became a singular pair for Lux Aertena – Separation and Unification. While both serve the same intent, they do so in two wildly contrasting manners.

Inspired by the works of Ansel Adams and the awe-inspiring photos of nature he took, the artist uses clouds and light to compose the two art works. To achieve his desired effects, the artist makes use of Terragen to synthesize the clouds and compose the works.

Separation is meant to depict the subtle shift in emotions that a listener goes through as he listens to the song and does so using distinct colors for different clouds. Unification signifies the grandeur of the song as a whole, unifying the different elements of the song together with a feeling of brilliance. Stemming from the teachings of Josef Albers, the artist uses placement, light and different colors to invoke the desired emotions in viewers. The artist also uses points extensively, with different form, color and relativity.

This pair of artworks aspires to help the viewer understand and appreciate the song even more by using the same techniques of separation and unification as in the compositions.
