cant remember the website but there is one where u can use your mouse to move a real rifle fitted with a webcam to it, it is on a motor system and when u click the button it actually shoots the rifle at whatever u are pointing at. I know it sounds surreal but its true.
This is my fave. It`s got night vision cameras on owls badgers and the osprey nest. I have it on nearly all the time. Interesting if your a nature lover like me.
