    Here is an interesting but useless piece of information.

    A fly landed on my screen. I moved the cursor around in a very aggressive manor but the fly would not move.
    I thought I wonder if they can tell that the cursor is only 2d and not a threat.
    I moved my finger toward it and it took off.

    Interesting.

    How does a fly work out that a 2d object coming at it is no threat?
