A classic 13 row Japanese Soroban with an optional digital display for practice.

Hold the Shift key while clicking on an Earth bead to also add the Heaven bead.


Release Notes:

Added a menu page with a link to the standard soroban, a practice soroban with a digital display and a direct link to a great website for abacus instruction.

Also moved the reset button away from the abacus beads so it won't get clicked accidentally during calculations and shifted the digit markers over one bead.

Added soothing wind chimes to the opening menu to calm you before you attempt to learn the abacus. ;-P

Good but very basic - It is an abacus. For learning the ropes, it is very handy. Pros You can click-hold the left mouse button and move multiple beads at a time. Have the option to either show the number that the current configuration corresponds to (Practice) or to not show the number (Soroban). The website linked by the "Instructions" button is very handy. Cons It does not support hotkeys, only the mouse moves the beads. The screen is not resizable. No volume control. No easy toggle between Practice/Soroban. Must return to the home screen and click on the other one to switch. Instructions opens in your default web browser, so you'll have to hit the esc button on your keyboard to get to it. No hotkey for hiding the application.
