I was curious what the CorelDRAW ui would look like if it were black so i decided to invert it, masking out all the areas that need to stay white. I thought it looked pretty cool so i decided to share it.
There is a small image posted in this thread and a larger one attached.
enjoy
You can do it automatically using a black theme for Windows, by changing colors or using a program such as WindowBlinds (stardock.com) or MagicDesktop (ommoo.net)
