The latest development version of fische includes PortAudio support, which enables it to run on other operating systems than Linux.

The Windows Version works quite well on Win7 (the only platform i can test on), with minor issues regarding frame rates and fullscreen switching.
If you do not know what a commandline interface is, this is not yet for you.

The OS-X Version runs without complaint on Leopard (again, the only test platform i have available). I had to use SoundFlower though, otherwise fische (like any other program) is unable to tap into the output audio stream.
