Having been a recent architecture student the one thing that really irritated me was pinning up my work on a pin board. Very rarely did my plans stay on the board through my whole presentation and hippy architect types often ended up with drawing pins in their bare feet.
So what if a large surface
could be given a static charge allowing one to easily and magically stick paper to the surface. Surely this is possible? And what fun it would be to stand near the thing with all your bodily hair standing on end!
If the plans were printed on blue felt . . . [contracts, Nov 30 2004]
Exactly what is needed here.

||This idea would simultaneously stop the use of drawing pins AND give static cling:
Use a *huge* balloon, and rub your head on it before use.
||static wears off though doesn't it? I'd trust pins more.
||Yep, me too, my legs are fine.
||There are post it notes available in 25"x30" size.
||HP flatbed pen plotters have this, though they're usually
instead of vertical. It's called Autogrip. Unfortunately, HP no
longer makes pen plotters.
||What you need is an electret board.
||After disassembling my HP 7210A (though without looking at
the circuit diagram that is surely available for it), I think the
Autogrip feature works dielectrophoretically [link], using an
AC voltage applied to interdigitated metal strips on the
drawing surface, under a plastic cover sheet.
