lightbox transformed into a LED matrix

My wife was given a lightbox for her birthday. The lightbox has slides in which you can put plastic cards with letters and pictures on them. In the box there's a lightsource consisting of white LEDs.

This box inspired me so I bought one myself to tinker with.

I tried to keep the box as much intact as possible. Apart from some holes to let the cabling out, the thing is unharmed.
In the box there are now LED matrix panels glued to the front-panel and an ESP8266 compatible MCU (Wemos D1 mini).
This MCU listens on the WiFi network for UDP packets. These UDP packets (192 bytes each) contain pixels, not text. 64x24 pixels, 1 bit per pixel.
The MCU runs Arduino with a custom program which can be retrieved from this page, also an example python-script can be downloaded which streams a webcam to it.
I had to add solder VCC/GND cabling to each individual LED panel because otherwise the matrixes would often behave strange.
