Just for fun.
When I was walking around for sightseeing, I discovered such a clock in the presentation area of a shop.
I thought, this could be a nice fun program to get implemented with tcl/tk.
After a quick search, I discovered that someone else already had the same idea.
Pls see here: wiki.tcl.tk/27622.
I just thought, it might be useful, to prepare an executable, so that everyone can give it a try.
Just download the executable and off you go.
Here is the download Link:
