Security without security!?

I was fooling around and dicovered this cool thing I use as a sort of 2nd line security (after my screen saver of course). Ok what I did was I moved my cursor to the bottom of the screen to make it hidden and presed print screen. Under paint I proceeded to press ctrl+v (paste) and my desktop came up. I saved that under my windows folder and then set it as my wallpaper. Still under prperties I checked the box that says "Hide Icons when viewed as a web page" (under the Effects tab). Then I made my desktop an active desktop by right clicking and my icons were there....or were they. No but it sure looks like it. The other cool thing about this is that if you turn your taskbar to autohide it looks like nothings running, nothing shows. I even went as far as moving the height of my taskbar to the smallest one. This is pretty cool. Now alls I need to do is change my startup screen to the same thing.
