In French (I think) Réglettes Cuisenaire

One improvement you could make to the rods (as suggested by Alan's email) is
to allow the placement of arrows on the rods as an option.
I would love the opportunity to test your artifacts and provide feedback
(feel free to ignore what you feel is not appropriate I do not get offended
easily ;)
Unfortunately I do not know how to open the mcz files :(
Some SIMPLE steps to download and try and/or pointers to documentation would
be greatly appreciated.
Thanks,
Stephen
