For some reason this makes me think of the movie Johnny Mnemonic, as in that movie they had to use selected images from television to unlock information. Well this system uses little icons selected in a certain sequence, more like a visual combination lock to access the computer.

To log in, you must find at least 3 of your pass icons. Note that not all of the pass-icons may be on the screen. But at least 3 pass-icons are always guaranteed to appear. What pass-icons appear on each screen cannot be predicted. However, once you find them you can follow them as they move, exit or enter the screen. The screen bellow shows the pass-icons highlighted in red.

A very different idea, and almost infintely complex if done correctly. I can see it now though. If my mom had to use a system like this…she would have it set up to be as easy as possible, something like the IE icon three times if that was possible. *sigh*
