Yes, I discovered that also in my testing of the example.

You discovered what I had discovered ... the example depends heavily on
the Physics library bundled with Pippy. I got lost looking at the
problem and gave up. But I did almost manage to convert the code to be
screen resolution independent. See 4a50004 ... the winning round
position check code has a FIXME attached, and I welcome input.

Quandry: we'd want subsequent users of the examples to be challenged by
the same problem, so why would we want to fix it for everybody? When
editing the examples recently I saw several improvements that I could
make but decided not to make them because I wanted the reader of the
example to make the same mistake as part of their learning.
Sharing in class context ... does this work? Can the journal entry be
For merging the improvements as part of the Infinite_monkey_theorem, we
would need to bring the change back from the user into the development
community, and provide feedback to the user. We might not be able to
depend on an e-mail path. So I envisage a small web application on
sugarlabs.org that would provide these features:
1. submission of example improvements, which are inserted into a branch
in a git repository, where the branch is named for the user,
2. status view of their submission branch, using a journal entry of a
3. download of other submission branches by users,
4. scoring and voting by other users.
Is there a web application that does this kind of thing already?
