This program generates a tone that seems to rise or fall forever.
It's sort of like the tone described in http://en.wikipedia.org/wiki/Shepard_tone except that this application allows you to adjust various parameters such as whether the tone is rising or falling, how rapidly it is doing so, and the ratio between the various components.
This is a Java JAR file that you download and run on your local system. It requires Java (not the same as JavaScript). Unlike a Java applet, it does not need a Net connection to run once it is installed. It can be run on Linux, Mac, or Windows machines as long as a suitable version of Java is present (I have Java version "1.6.0_20" for Linux) and the machine can play audio.
You need only minimal technical skills to install and use the program. You may need to know how to make directories, download files, and run other simple command-line commands. You also need to know how to use your computer's audio capabilities.
To use the program, download the JAR file into a convenient directory and then follow the instructions in the Readme file.
The source code is included so that you can modify the program if you want to, but you do not need that level of skill to use it as-is.

I chose the name "Floomptagorpt" because I like making up nonsense words, search engines came up empty on it, and it may be easier for English speakers to pronounce than "Plergb".
