LED ball

[Work in progress]
A 3D printed sphere with 576 holes for LEDs, and an additional one at the bottom for a micro USB connection. The circuit is a matrix of 24x24 LEDs controlled by a custom logic circuit and a microcontroller. It is controllable over USB by a Python script or by writing routines for the embedded microcontroller (Arduino/Teensy).

I've created a MATLAB script to generate the points so that they are as equally spaced as possible, This can then be copied into an openSCAD file to
