In the referenced article, Brent Southard describes Jitter-Rid, a
plastic filter for reducing interlace filter on the Amiga's 1080
monitor.
    I have my doubts.  It sounds like the piece is either a polarizing
filter or a simple neutral density filter.  In either case, its effect
is much the same as simply turning down the brightness knob on your
monitor.  The only additional effect would be a reduction in room-light
glare if the Jitter-Rid has a non-glossy surface.  Brent, do you use
your Amiga under flourescent lights?  They noticeably increase
interlace flicker, since they flash at the same rate as the screen.
(I've noticed this effect on the Sun workstations at the office.)
    Has anyone thought about how to build a frame buffer which would
store and display an entire interlaced image all at once?  Seems to
me that such a box would be less than the $500 for a new monitor.
