Inverter

Reduce your eyestrain while long computer usage. Black text on white background is not the best option to read texts in office environments. With this small app, you can invert your screen colors and make it less exhausting to read. The second feature is adjusting display gamma level.
Unlike many accessibility tools, it does not create a terrible overlay window, and it does not consume any extra system resources.

Project is written entirely in C# and can be compiled under free SharpDevelop IDE.

Disabling other tools, that are controlling graphics, may be required. On some configurations, inversion must be triggered twice, before it will work.
