Austrian artist and architect Peter Jellitsch measured Wi-Fi activity and produced this artwork, Bleecker Street Documents, which includes a CNC milled sculpture.

The piece is named for the apartment where Vienna-based Jellitsch crashed during a New York residency for 45 days last year. “I used a radio-wave-measuring device several times a day in the apartment and translated the measurement result daily on paper,” he tells Co.Design.

With hundreds of handwritten data points in hand, Jellitsch set out to build a physical model of his findings. He began with a flat white plane and plotted the data points across it chronologically. At moments when the Wi-Fi signal was strong, he raised the vertice associated with that day and time. When it was weak, the vertice stayed flat. The resulting model is half model, half calendar; a three-dimensional visualization that charts signal strength over time. He milled the final model on a CNC machine and mounted it on a shipping pallet.
