... Surfing the net my eye fell on a device called "Divoom".
It reminded me of a little toy I liked to play when I went to kindergarten (more than 55 years ago... ), it was called "Chiodini colorati".
So I made this little script to emulate it, ...maybe some kids will have fun playing with it.
The attached zip file contains the script and also some "pixel art" files ready to be loaded.
P.S.
Thanks to @KaFu for it's _WinSetClientSize() function and to @InunoTaishou for it's CaptureWindow() function (references are in the script)
