LOL, I am c't reader as well and found it funny, but too tricky to find out the time.

Not sure, if my answer ist interesting to you.
At the moment I work on a project (the layout is not pefect as you see) for a clock.
I'll attach you a snapshot.

And it is not too hard. I found this clock by good luck into the free compontent tvplanit / gadgets.
So if you like clocks, have a look at it.
You even can change the faces of the analog clock and the size of the digital digits.
3 runmodi are included: normal watch, contdown and alarm.

- Simple UX
- Resizable
- Skin support
- Customable layout and background color
- Multiple clocks

I do not have YouTube account, so I posted the quality-downgraded animation here:

Components seems to be nice. I try to install the first one: CodeBot. I get an error in compilation of lpk:

",45) Error: Can't determine which overloaded function to call"
