On Halloween, we replaced our front door's screen with a rear-projection
screen (OK, so it was a light blue sheet and a few layers of black
gauze on top to cut reflectivity). We projected the show (recorded to
videotape) onto the
screen from inside the house, with several speakers mounted just inside
as well.
The exterior was darked out, except for a few candles.
This small show demonstrates some of AFX's multimedia production capabilities, though it was done very quickly for the fun of it, and this shows... But it really impressed the kids, and made some cry. Impressed even the teen-age boys; some wanted to come learn how to do it!
