sticky VU-meter for ALSA

[Florin Andrei <florin@xxxxxxxxxxxxxxx>]

I'm looking for a stereo VU-meter that has the following characteristics:
1. can monitor any arbitrary (configurable) ALSA output
2. is "sticky", so it stays displayed when I switch between virtual 
desktops in my Gnome environment

I guess #2 means it's either a Gnome applet, or some kind of OSD-based 
thing (with the aspect of the "LEDs" configurable in terms of size and 
coordinates).

Suggestions please?
