How would I draw something on the screen ? not the console window but the entire screen, preferably with the console minimised.
Also, would it show up on a printscreen ? It better not :P
What I want to do is create something like a layer on top of the screen that only me and my aplication are aware of yet still be able to use aplications as usual.
I thought the drawing part would have been done thousands of times by now but google has failed in returning any promising results.
