This is very sad to hear. I had the privilege of working with Loyd briefly in 1980 or 81. I was commissioned by The American Productivity Center in Houston, TX to create a stereographic hologram of their new building as part of the building's dedication and opening. I was provided architectural drawings of the four or five story building. A friend in Dallas, with access to a robust graphics computer with 16mm camera head, and I converted the drawing dimensions to a plus and minus 32767 XYZ world (by hand). We then entered the digitized XYZ coordinates of the building into the computer and selected an "eye view" location for rotation of the building about the Z axis. The computer generated the frames of the building as it rotated 360 degrees while a 16mm B&W camera took two frames of each rotational view. I shipped the resulting film off to Lloyd who then printed the multiplexed hologram for me. The 360 degree film was mounted in an appropriately lit, motorized plexiglass right cylinder and bundled into a furniture grade kiosk for final presentation.
I could not have done it without Lloyd's amazingly generous, meticulous and patient personality.
