Check out what is going on in the Cincinnati in4 pod. The in4 team has recently been recycling the paper roll tubes to experiment with shading. When completed, the one window will house 350 mobile tube pieces, nearly 35 tubes from our printer. Depths range from 2.5 inches to 5.5 inches. The winter solstice proved to need a 4 inch tube to eliminate all morning direct sun.
The directional viewing loss is not necessarily a bad thing, but the direct light is cut almost completely. The only time there is glare is from evening sun reflecting off the courthouse windows.
If you have any observations, please feel free to share with the in4 team. Many have commented already and they would love to hear what you think.
