Alright,
this is for the adventurous:
I made a status area plugin which replaces the standard clock in the status area with a binary version.
Please be aware that this package is still a work in progress and hence may feature a number of pitfalls.

If you want to try it you can find the latest version in extras-devel.
The package is called "binaryclock-plugin".
Installing this will replace the standard clock with a binary version.
To get the standard clock back just uninstall binaryclock-plugin as usual via the application manager.

I'll open a dedicated "announce-thread" once I think this is mature enough to be released into the wild.
So long, your comments are highly appreciated.
Note: a settings dialog is available via the status area menu.
Though, the settings are not stored yet.
Consequently, the changes are lost after, e.g., a reboot.

P.S.: Currently, somehow the uploaded package description and hence the package website is way messed up.
The application manager displays the description correctly, though.
I am working on getting this fixed.
