Does this actually work for anyone? I tried it today at school (lol my school has like 10 Toshiba TVs) expecting to scare the **** out of my science teacher (hes paranoid about ghosts and aliens and stuff) and it didnt work. Is it because I was kinda hiding my PSP under the table (lol)? Do I have to like stand in front of it? I wish it worked cuz that would be sooo funny.
