We're doing Alice in Wonderland and would like to have our Alice "fall" through the rabbit hole instead of just implying that she's falling offstage.

I read somewhere online a suggestion to dangle Alice in front of a scrim on which the contents of the rabbit hole (cupboards/shelves with a variety of objects in/on them) are projected from behind. Projected with what? A slide projector would be be noisy and choppy.

Thoughts? Thanks.
