Old but fun wallpaper trick

Oh awesome. It's a cool little fading trick. My favorite trick to do on others is still disabling icons/right-click and making the wallpaper a screenshot of current desktop.

This.

That's actually what I thought this thread was about.

even more fun at work.

I used to do it to computers in the computer lab at school all of the time. I also liked going around an unplugging one random device from every computer I see. Keyboard, mouse, whatever. I bet the IT guys hated me.

Great minds think alike, I do the same along with reassigning printers at the labs at my community college, loads of fun!
