Almost great

I really like this program. For a while, I didnt notice anything wrong with it, until I wanted to change my pass pattern. It turns out, you dont need a password or even the original pass pattern to change the pattern. Therefore, if my computer is not locked, someone can go into my preferences for this program and change my pass pattern, thereby locking me out of my own computer. Its a good prank, but could become very frustrating, especially as I dont know of any backup plan for getting locked out using this program. Maybe a shutdown? Havent tested it.

Seriously, too many nicknames about Screensaver + free
