You need Compiz and Color Filter plugin to use this!
This is a color filter, which inverts the grayscale (black to white, white to black) but keeps the same color.
It is useful for reading text on your monitor for a long time. If your eyes hurt from reading black text on white background, this is for you.
1. If white text seems too bright still, use the brightness plugin in Compiz to lower the brightess to about 80 or 70.
2. You can use this filter along with the Negative plugin from Compiz to invert the color. TRY IT! (watch Avatar with it?)
1. (optional) copy the file to /usr/share/compiz/filters/
2. Open ccsm
3. Open Color Filter
4. Click New and browse to the file
5. Use the keybindings to enable the filter
Note: Turning the plugin on has no guarantee that the filter is the one I gave you. You need to switch filters to the right one.
Google page with the filter turned on.
A white box appears around the window (when you have a shadow in your theme?)
Fix: Turn off Filter window decorations in Color filter plugin.
May not work in Ubuntu 10.04
