last-updated: August 11, 2013

[Japanese] [English]

You have fun with this "Hey" button, which talks and counts the number of pushes. A counting server collects the numbers from buttons over network and show them and the total. These programs run on a Java Virtual Machine (JVM) and support all plaforms that have a JVM. They can be launched by just a few mouse clicks without prior installation as long as the computer has JRE installed.
