I do not know exactly, a few days. I mean the tiles only. I was making about 40 tiles per day (well, per evening, to be exact). The most frustrating fact is that the tiles are not perfect - I cut them myself out of Kassett folders from IKEA (
http://www.ikea.com/us/en/catalog/products/10168254) - 101 tiles out of one folder

. I'll make some photos and place them somewhere for you to take a look.
As to an alternate language page - that was not what I had in mind, and that's a big project, just as you said. I was thinking of a simple download sub-page with various translations of the rules.
I uploaded my translations here:
http://files.mail.ru/0B2O0W. You can have a look at them and tell me if anything needs to be changed. Known issues:
1. I have not translated the "Acknowledgements" sections
2. I have used different fonts, because the ones recommended did not have Polish lettersWith your permission, I'll keep on uploading my translations this way and notify the community in this thread until you decide about hosting them (or not).
EDIT: moved files to new place, see the first post in this thread
