Those with a "*" above have a "Teach" mode for addition, subtraction and just added multiplication, division, square root and cube root. Multiplication, division, and roots works best on "Lee" versions as they can hold values in auxiliary abacii.

Now with beginnings of some language support for French, Spanish, Dutch, German, Norwegian, Russian (I need help from translators see line 72 or so of abacus.js). It is all driven by a single JavaScript program with input parameters in the html.

Let me know of any bugs... (yes, the Lee's Abaci has some alignment issues if you change number of rails). If there is a abacus design not featured that you want to see, let me know. The Java below has more features (and no alignment issues), but can no longer run in your browser ... sigh.
