UPDATE on 18/06/2020: I've implemented a simple analog clock in my own
programming language, it's runnable on Linux (both 32-bit and 64-bit). You
can download the source code here, and, if you
are willing to accept the risk of infecting your computer with some virus
on my computer (rather than compiling that program from source), you can
download the executable
here
(the executable is called
analogClock.elf).
UPDATE on 09/08/2020: I've managed to compile the
Analog Clock program written in my
programming language to be runnable in a browser that supports
WebAssembly.
