I make a Calculator example to put it in Examples in Lazarus, you can modify the header to put the right license, check it please.

You can notice there is a "calculators.pas" in "lib" folder have TCalculator, it useful to make any calculator application, the example it is demo how to use it (oh my bad English).
May be that "calculators.pas" move it in "lcl" folder or any path can easy to access it.

Also i compiled it for WinCE/ARM already founded in zip file

I would suggest Public Domain for examples, so that anyone can readily use the code in their own projects. What do you think?

Putting examples in a Wiki or Forums make it difficult to search, fix or modify the code, and it so hard to make SVN repository for "lib", "demos" then add users to it (like me) to commit junk code (examples and small projects).

A wiki might be ideal for it. Maybe not the lazarus wiki, but maybe a wikispaces or some other wiki.
