What I would like is a screen saver that, when you sit down at the computer, will not unlock until you answer the question “What did you come to the computer to do?” and then displays that answer prominently but not obnoxiously on the screen (perhaps in a floating or semi-transparent window) until dismissed. Perhaps to dismiss it you would have to type in some text indicating what you had done about the whatever-it-was. Perhaps the prompt and the reply would be recorded, time-stamped, in a log file.

This is intended to address the problem of going to the computer and getting sucked in by LiveJournal or Facebook or Twitter or such for an hour before you realize you didn’t even do the simple five-minute thing you went to the computer to do.

Does this exist (for the Mac, please)? Or do any of you have the skillz to write it?

(Yes, it could be overridden by typing gibberish, and after using the thing for a while one would probably get in the habit of doing so. It’s as hard to outsmart oneself as it is to tickle oneself. But one must try…)

Getting up and doing something else now.
