Java XEyes is a re-implementation of the famous Xeyes program found on older Unix and X-Windows computers. Just start the Java XEyes application, and the eyes will magically follow you around as you work. It makes work interesting again.
Although this program has been bundled for Mac OS X systems, it uses Java, and requires Java 6. This is commonly available on Mac OS X 10.5, 10.6, and newer Mac OS X releases.
