Abacus iPhone App Offers Alternative to the Calculator

In Japan, it's not uncommon for someone to still do math on their abacus. I even had to take an abacus class during summer school as a kid—and I didn't even go to a Japanese school. In a way, it makes a lot more sense than a digital calculator. Anyway, some clever developer created this abacus app for the iPhone. You use the touchscreen to move the balls up and down to do your calculations, and i has a motion sensor so that you can shake the phone to clear it. You can see a video of it in action here.

Can you share any pages that would explain the usage of abacus as it is used in Japan? :)
