This is an idea I've had for years, but never posted
I thought it was not
novel. I did a Google search for the title just now,
and didn't find
The idea is to make a door that works like automatic
sliding doors on stores, but
instead of one piece on each side,
it's divided into
pieces, each one about
an inch to several inches high. When you approach the
door, these pieces open like
a regular automatic sliding door, but instead of all of
sides opening all the
way, only those pieces that are actually in your way
and each one only
opens as far as necessary to get out of your way. This is
done using computer
vision, as well as proximity sensors on the tips of the
sliding pieces for fine
guidance. Each piece is equipped with a separate motor
(which can, obviously, be
smaller than a motor that would move the whole door).
The effect is that the opening of the door is the same
shape as your body (plus whatever you're carrying), and
the rest of the space covered by the door remains closed
while you pass through it.
The point of this is to reduce air exchange between the
two areas separated by
the door, whether this is to conserve heat, humidity, or
clean air, or for whatever
other reason you want.
This is probably why the Idea here will probably stay HalfBaked. [Vernon, Aug 29 2016]

||Maybe it could be achieved in a lower technology form by
making a sort of rubbery diaphragm arrangement that is
secured somewhat more tightly at the top end and also at
the bottom end, thus elongating vertically the aperture
that you plunge into and consequently on the other side,
||I like this. You could make the sections out of faux brick and
go for the Station 9 3/4 Harry Potter effect.
||Will it make the traditional "Zwishhhhh" sound when it moves ?
||Sealing could get expensive...
||Thanks [LimpNotes]. Where can I buy one? I imagine it's now
considerably improved vs. that video from 9 years ago.
||Looks like they had a website up at some point, but its down now. The name of the product was E-Taf Automatic Door.
||How about "Matryoshka Door"?
||Of course before I read your full description I was
imagining the door with a whole lot of nested cut-
outs in the shape of people, making the name more
