With this application you can shake the Soroban (Japanese Abacus) and enjoy the pleasant sound that is created.
You can shake it to the rhythm of the music you are listening to or simply perform a solo.
The sounds will change according to the speed and direction you shake it and also the way you flick the beads.
Please find your original performance style.
Of course this crackly rhythmical sound will also be produced if you use this Soroban as a normal Abacus.
