    In this work we demonstrate the use of a commercial CO2 laser cutting system to etch the surface of silica aerogel monoliths without causing overall structural damage to the monoliths. Text, photographs and other images can be readily reproduced on an aerogel surface. The visual appearance of the etched aerogel sample depends on the orientation of the sample and the viewer relative to the light source, which renders this approach visually attractive for applications in fine art, fenestration and architecture.
