Impulse - PulseAudio Spectrum Analyzer is a bit of eye-candy for your desktop. It is a widget that displays a graphical spectrum analyzer on your gnome desktop. It is written in python and uses GTK and cairo graphics to generate the animation.
The cimpulse module creates a pulse audio connection context that reads the output stream from pulseaudio in a thread natively which can then be read from python. You can specify cimpulse to either output the raw stream or output the fft of the raw stream.
About Screenlets:
Screenlets is the name of both a set of independently-developed widget applications and the widget engine which runs them. The engine runs primarily on X11-based compositing window managers, most notably the Compiz (under Linux) architecture.
Until 0.0.14, screenlets were exclusively scripted in Python and drawn in SVG. Afterward, support was added for web widgets (widgets which are written in HTML, JavaScript and CSS, similar to widgets for Apple Inc.'s Dashboard).

1) Install packages ( Ubuntu ):
sudo apt-get install python-gtk2 python-cairo libfftw3-3
