    The address wasn't understood

    Firefox doesn't know how to open this address,
    because the protocol (itmss) isn't associated
    with any program.

Nope, can't be bothered.

It's a link to an itunes application. I think I'd prefer not to install random applications on my computer, though.

oh apparently it opened a window in chrome as well. It's a link to that app where it generates a rule, gives you three numbers that follow the rule, and you have to guess other numbers and see if they follow the rule, and eventually you have to guess what the rule is.

There was a youtube video floating around a few weeks ago. It's really not worth it.
