Led Table

This is a LED table, but not just LEDS placed under the glass surface. Those LEDs are on the floor level, and stretch infinitely.

The table is the hollow wooden structure, with the glass at the top and 34x34 cm PCB at the bottom. There are four mirrors at the walls, creating the infinity effect when you move around.  I had the PCB (left from some old project), with the MCU and drivers for 4040 multiplexed LEDs. Not all of them are used here, but the firmware dims them individually at random, so most LEDS are dimmed on or off very slowly. The only exception is the white net, created of white LEDs, which are always ON. There are only 3x3 squares on the PCB, all others are their images in the mirrors.
