Crazy idea... dry ice curtain -- could it work?



I am doing an event and I want to make a special effect as guests
leave. I want to project some video onto something that the guests
walk through as they leave.

I am thinking of this, wonder if I am dreaming, or if it is possibly
do-able.

I am thinking of a curtain of Dry ice CO, one which they could walk
through, but that I could also beam video onto.

To accomplish this I was thinking of making slightly pressurized
system* that I could put a horizonal PVC pipe above the heads of
guests, and have the CO come out of the pipe with tiny pin-holes
drilled every inch (or so) The CO would flow out of the holes and fall
to the floor, hopefully in an even enough pattern to allow a "surface'
to project video onto.

Is there any chance it would achieve the effect I am looking for?

I would love to have it outdoors, but obvioulsy any wind would scotch
that Idea, so I am thinking I would be doing it just inside the doors,
(with proper ventilation of course).

If that wouldn't work, could it be done with a smoke machine?

* the "pressurized" system would be safe, let's say a 5 gallon bucket
with lid, and hose leading out to elevated horizontal dispursal pipe.
I would just put an extra hole in the top of bucket lid, then put a
heavy book or something on top acting as a simple "pop off" valve, so
it would provide enough pressure to push CO up through dispirsal pipe,
but there would never be any chance of pressure building up to
dangerous levels.
