Laptop internal camera cover for the paranoid

Call me paranoid, but I don't like the idea of having a camera pointed at me every second I am on my computer. I have a Lenovo laptop that has an internal camera. Sure, it has an indicator LED next to it that illuminates when the camera is on, but I happen to know that these indicator LED's can be turned off via software. If some hacker ever gets into my computer, he/she can see me and everything around me. I'm way too paranoid for that. So, I drew up a litte sliding cover to fix the problem
