show that the pencil's movements appear oddly purposeful, as if a consciousness were driving the mark-making; but in shots from afar, the mechanical process is clear. A Line Describing the Sun (2010) His work A Line Describing the Sun (2010) is a two-channel video that documents Lamson melting the desert floor with a Fresnel lens into a line of black glass. He follows the path of the sun moves through the sky, hence the chosen title. With the help of a single assistant, the filming process involved performing this event over five days, capturing everything from wide high-angle shots to macro shots of the melting earth. Solarium (2012) In the site-specific installation structure Solarium (2012), was located at the Storm King Art Center in Mountainville, New York. The installation structure with three species of citrus trees grown inside. The 82 sq ft experimental structure is a functional greenhouse constructed of a steel frame and panels of caramelized sugar. To create the panels in an "amazing spectrum" of hues, Lamson concocted recipes he made himself, simply boiling refined white sugar until it turned specific shades. The resulting shades vary from clear to opaque black, with saffron, flame orange, primrose, and deep burgundy in between. Lamson believes that when you approach Solarium up Storm King's grassy hill, you experience the Andrew Wyeth sensibility of "the sanctuary in the landscape." From the outside the structure gives the impression of a chapel of stained glass, and once they are inside, the viewer is able to understand the color of the panels better. These panels also create a colorized frame through which to view the landscape. There is a shifting experience between the unique color and texture of panels themselves as they age and change in the sun. The structure is centered on a miniature lemon and orange trees symbolizing his interest in sugar as a fundamental requirement for life. All plants create sugars through photosynthesis. Lamson was interested in how the red-yellow light coming through the caramelized panels would affect the plants themselves and wanted to see if they would one day bear fruit. This possibility suggested a recursive materiality at play between the color of the light and the color of the fruit that the trees might produce.
