Electronic Connection Machine 2

Before we had GPUs, before we had multiprocessor personal computers, and before we all settled for beige computer cases there was the Connection Machine 2, a massively parallel hypercube-based arrangement of thousands of microprocessors.
The original, with its many blinkenlights, was 1.5 meters across and so this 1:10 scale version is 15 centimeters or a little less than 6 inches across.
Each of the four front panels include a 16 x 9 LED panel and the unit is shipped with an Adafruit QT Py to drive them.
An example script is included to turn your Connection Machine into a clock!
With help from a couple of full sized Connection Machine owners I've reproduced this wonderful machine down to the smallest details, including the custom vents that run between the main cubes.
