On opposite sides of a corner, a nod to J.J.P. Oud’s housing, where a repetitive system had to bend to the irregular streets, two ESP32 microcontrollers with single LEDs blink in sync. A motion sensor breaks their rhythm whenever someone passes, and a Raspberry Pi with an LCD screen records each passage as a notation of dots and lines.
