This Ping Pong LED Wall is made of large PCBs sponsored by: PCBWay pcbway.com/?from=bitluni
It consists of 1920 ping pong balls as pixels and is controlled by an ESP32. The parallel data lines allow over 74fps and a camera live feed. The panels are easy to exchange in case of failure and built in bus lines and configurable mounting plates allow to build a display of any shape. My Arduino library provides the LED driver and a graphics interface to draw and display anything.
