Hello all.
First of all, I would like to make clear that this in not a C programming question, but it has to do with it.

About a year a go I made a program in C that computes the day of the week of a particular date, after christ.

I wanted to have this program running, but not in a computer; instead, in a mechanical machine. With a little time, I solved the thing with 2 small concentric discs. The discs are marked with CENTURIES, YEARS, MONTHS, and DAYS. All you have to do is rotate the discs in a manner so that you can compute the day of the week by watching trought a little hole in one of them. Unfortunately, you can compute dates only and only if the date is between 1600 and 2000.

Now the question is: Would someone be interested in buying such a thing and hang it on the wall of his/her home?
I live in Mexico City, and no one here is interested in nowing the day of the week he or she was born, or when a particular date is Saturday or Sunday ????

But, maybe if I go to the piramids of Teotihuacan, and offer this thing to the foreing people that comes to my country to see something curious, maybe I would have some luck. What do you think ????

This has nothing to do with C programming. Also there is a General discussion board that would be better suited for this. Although, I would have to check but I this may fall into the advertisement rule.

Market it as a genuine Aztec, Spanish, etc artefact, whichever one they like the sound of better, and surely someone will buy it eventually.
