Gnome Color Calibrator actually is just a gamma tool. Probably good 
enough for most people though. At least something like this should be 
included in Gnome. =)

In any case, ICC profiles are much more than just gamma. The ICC profile 
can tell you what colors the device support (important!), what the 
dynamic range is and things like this.

Another cool thing to support is color proofing - the emulation of 
another color profile. This is very useful as it lets you (with some 
limitation) see how the colors will look like on another target. For 
example another monitor, a photolab printer etc.

Many monitors has a larger color space/gammut than sRGB. Therefore is 
color proofing a needed tool if you want to see how your images will 
look like on the web for other viewers.
