GE had a projector that wrote diffraction patterns on an oil film with
an electron beam and could do color!  The projection tube had a
palladium diaphragm that let hydrogen from the breakdown of the oil
diffuse out. I was trained on its care and feeding, but never went on
one of the few conferences they booked.  Any LCD projector can, of
course outperform that refrigerator-sized box by a LOT.
