We cling healthy ammeters to a PC via Arduino

I hooked up a pair of healthy ammeters to the Arduino - unscrewed the shunts from them, and through the resistance on the PWM I hung the outputs.
Immediately I remembered 3 application options (use zero, one pampering :)):
- measurement of processor load (just now, 2-core processors have gone);
- displaying the speedometer and tachometer readings from racing games;
- there was also an idea to make VU-meter for Winamp - until the hands reached.
Actually, here is a photo to estimate approximately how it looks:

And a photo showing the measurement of loading a 2-core WinRAR processor:

There is also a video with a little of the revised version of TORCS:

From my blog ( arduino-ru.blogspot.com ) you can download the source of all the pampering

PS This was the first post that stuck in the sandbox, and for which an invite was received. As it turned out, it does not automatically go to the blog, so I put it here. :)
