I think Konfabulator messed up my comptuer somehow, so I don't use them anymore. I liked them too....
I find that THE BEST iTunes controller thing out there is M-Beat...
As you can see, you can have a floating window and choose its color and opacity. Then you can assign keystrokes for iTunes commands... I use stuff like opt+cmd+Right arrow for "next track", etc. so it's easy to do and I don't get it mixed up with any other application's shortcuts. There's other options to use in M-beat, but that's all I use.
Another weather thing is WeatherPop, which puts it in your menu bar.
But yeah...here's my pic.
