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. |
