The "trees" against the windows were printed on an Ultimaker 2 using KS, taking about 3 months and 18kg of PLA. Each square pocket allows a unique amount of light transmitted, giving colors ranging from ivory to taupe during daylight (at night they are white). The depth of the square pockets is up to 6" deep, and the effect is to diffuse the sonic reflection from the back of my flat-panel speakers, giving a less-distorted and more natural acoustic stage.
