I wrote pyBCD Binary Clock Screensaver 1.0 in Python using the Pygame library. As for why I wrote it, I wrote it because I think BCD clocks are cool. If you’re reading in Arabic numerals then the terrorists have already won.
To download pyBCD Screensaver, click the following link: http://chrisuzal.com/py_code/pyBCD_screensaver.zip
It contains the source code, a Microsoft Windows screen saver file (.scr) and the General Public License.
The most important file is the SCR screensaver file. Copy this to C:\Windows.
After that, open your screensaver options. You should find “pyBCD_screensaver” is now in your list of available screensavers. Choose it and click okay.
When your computer idles, it will display the time in BCD.
“It displays,”, you say, “but how do I read this?”
