Invisible Post-it notes.

No more little yellow notes...

Ok. They're basically invisible Post-it notes. They have a sensor so that ink turns them invisible, but the writing stays. This way you won't have any ugly yellow notes posted all over, and you can make the notes overlap...

       Magic post-its, eh? [Marked For Invisibility]

       Not inherently impossible if we substitute "transparent" for "invisible" - 3M makes both Scotch Magic tape and Post-It notes, so they might well listen to you.   

       Trying to figure out why you want invisible ink too.

       The ink doesn't turn invisble, the ink being put onto the note makes the note invisible.

       will one little dot of ink do it?

       Why not start with it clear? (Like Scotch/Sellotape.) A whole lot easier to manufacture.

       But it wouldn't be nearly as cool.

       Ink that turns paper invisible? Uh uh, no way. I call "bullshit."

       If invisibility were a possibility, I think Post-it notes would be low on the list of priorities...

       [mahatma] has hit the nail on the head. the point of notes is to see them. the reason they are bright colors is to *improve* visibility. with no background, the black or blue ink on your note would blend in to the clutter on your desk and you'd never see what you wrote.
