Alright I am soooo angry! I totally invented this in high school in my physics class as our final project in 1998.  Totally should have gotten the patent right to this.  It is like the 4th item that I have lost to someone else!  I also thought of Netflix for both movies and video games before it was popular.  I also had the idea for Gametap the online gaming community!  Guess I should act on these ideas before someone else does!
