some touch buttons allow control of the display, switching from one city to another or changing animation.
a PIR sensor and ambient light sensor are included, to switch on LEDs only when necessary, at the right brightness.
the LED matrix is designed on OpenSCAD to be laser cut, with a parametric method which allows to be tweaked for other applications.
